² tn The Hebrew term קָלָה (qalah) means to treat with disdain or lack of due respect (cf. NAB, NIV, NRSV “dishonors”; NLT “despises”). It is the opposite of כָּבֵד (kaved, “to be heavy,” that is, to treat with reverence and proper deference). To treat a parent lightly is to dishonor him or her and thus violate the fifth commandment (Deut 5:16; cf. Exod 21:17).

¹ sn Now the reference to the commandments (plural) in 15:10 have been reduced to a singular commandment: The disciples are to love one another, just as Jesus has loved them. This is the ‘new commandment’ of John 13:34, and it is repeated in 15:17. The disciples’ love for one another is compared to Jesus’ love for them. How has Jesus shown his love for the disciples? This was illustrated in 13:1-20 in the washing of the disciples’ feet, introduced by the statement in 13:1 that Jesus loved them “to the end.” In context this constitutes a reference to Jesus’ self-sacrificial death on the cross on their behalf; the love they are to have for one another is so great that it must include a self-sacrificial willingness to die for one another if necessary. This is exactly what Jesus is discussing here, because he introduces the theme of his sacrificial death in the following verse. In John 10:18 and 14:31 Jesus spoke of his death on the cross as a commandment he had received from his Father, which also links the idea of commandment and love as they are linked here. One final note: It is not just the degree or intensity of the disciples’ love for one another that Jesus is referring to when he introduces by comparison his own death on the cross (that they must love one another enough to die for one another) but the very means of expressing that love: It is to express itself in self-sacrifice for one another, sacrifice up to the point of death, which is what Jesus himself did on the cross (cf. 1 John 3:16).

¹ tn Technically this ὅτι (Joti) clause is subordinate to the verb περιπατῆτε (peripathte) at the end of v. 6, giving the reason why the readers should walk in the commandment to love one another. But BDF §456.1 notes that subordination “is often very loose” in such cases and can be translated “for.” Thus the ὅτι assumes something of an inferential sense, drawing an inference based on what has preceded.

¹ tn The verb רָצַח (ratsakh) refers to the premeditated or accidental taking of the life of another human being; it includes any unauthorized killing (it is used for the punishment of a murderer, but that would not be included in the prohibition). This commandment teaches the sanctity of all human life. See J. H. Yoder, “Exodus 20,13: ‘Thou Shalt Not Kill’,” Int 34 (1980): 394-99; and A. Phillips, “Another Look at Murder,” JJS 28 (1977): 105-26.

³ sn The reference to the darkness…passing away and the true light…already shining is an allusion to John 1:5, 1:9, and 8:12. Because the author sees the victory of light over darkness as something already begun, he is writing Jesus’ commandment to love one another to the readers as a reminder to (1) hold fast to what they have already heard (see 1 John 2:7) and (2) not be influenced by the teaching of the opponents.

² sn The idea that love is a commandment is interesting. In the OT the ten commandments have a setting in the covenant between God and Israel at Sinai; they were the stipulations that Israel had to observe if the nation were to be God’s chosen people. In speaking of love as the new commandment for those whom Jesus had chosen as his own (John 13:1, 15:16) and as a mark by which they could be distinguished from others (13:35), John shows that he is thinking of this scene in covenant terminology. But note that the disciples are to love “Just as I have loved you” (13:34). The love Jesus has for his followers cannot be duplicated by them in one sense, because it effects their salvation, since he lays down his life for them: It is an act of love that gives life to people. But in another sense, they can follow his example (recall to the end, 13:1; also 1 John 3:16, 4:16 and the interpretation of Jesus’ washing of the disciples’ feet). In this way Jesus’ disciples are to love one another: They are to follow his example of sacrificial service to one another, to death if necessary.

³ sn The first day. The exegetical evidence suggests the word “day” in this chapter refers to a literal twenty-four hour day. It is true that the word can refer to a longer period of time (see Isa 61:2, or the idiom in 2:4, “in the day,” that is, “when”). But this chapter uses “day,” “night,” “morning,” “evening,” “years,” and “seasons.” Consistency would require sorting out how all these terms could be used to express ages. Also, when the Hebrew word יוֹם (yom) is used with a numerical adjective, it refers to a literal day. Furthermore, the commandment to keep the sabbath clearly favors this interpretation. One is to work for six days and then rest on the seventh, just as God did when he worked at creation.

¹ tn The form is a Piel participle from קָלַל (qalal), meaning in Qal “be light,” in Piel “treat lightly, curse, revile, declare contemptible, treat shamefully.” (See its use in Lev 19:14; Josh 24:9; Judg 9:26-28; 1 Sam 3:13; 17:43; 2 Sam 16:5-13; Prov 30:10-11; Eccl 7:21-22; 10:20.) It is opposite of “honor” (כָּבֵד, kaved; Qal “be heavy”; Piel “honor,” as in 20:12) and of “bless.” This verse then could refer to any act contrary to the commandment to honor the parents. B. Jacob (Exodus, 640) cites parallels in Sumerian where people were severely punished for publicly disowning their parents. “21:15, 17 taken together evoke the picture of parents who, physically and verbally, are forcibly turned out of the house (cf. Prov. 19:26)” (C. Houtman, Exodus, 3:148).

¹ tc Most mss (א*^,2 C L W 0106 33 Ï) have an expanded introduction here; instead of “For God said,” they read “For God commanded, saying” (ὁ γὰρ θεὸς ἐνετείλατο λέγων, Jo gar qeo" eneteilato legwn). But such expansions are generally motivated readings; in this case, most likely it was due to the wording of the previous verse (“the commandment of God”) that caused early scribes to add to the text. Although it is possible that other witnesses reduced the text to the simple εἶπεν (eipen, “[God] said”) because of perceived redundancy with the statement in v. 3, such is unlikely in light of the great variety and age of these authorities (א¹ B D Θ 073 Ë^1,13 579 700 892 pc lat co, as well as other versions and fathers).

¹ tc The translation here follows the reading στήσητε (sthshte, “set up”) found in D W Θ Ë¹ 28 565 2542 it sy^s,p Cyp. The majority of mss here read τηρήσητε (thrhsete; א A L ˹³ 33 Ï co) or τηρῆτε (thrhte; B 2427), both translated “keep.” It is hard to know which reading is best: On the one hand, τηρήσητε/τηρῆτε has much stronger external support, but στήσητε is a more difficult reading. What makes “keep” suspect is that it appears in two different forms, suggesting independent alterations of a difficult reading. Further, scribes may have been influenced by the preceding “commandment of God” to change the text toward “keep” (TCGNT 81), a common enough expression (cf. Matt 19:17; John 14:15; 1 Tim 6:1; 1 John 5:3; Rev 14:12). Thus, the more difficult reading is “set up.” Also, the more natural opposite of “reject” (ἀθεῖτε [aqeite], literally “you set aside”) is “set up.” However, the Western reading may have been influenced by Exod 6:4 or Heb 10:9, but this likelihood seems remote. Thus, “set up” is more likely to be the original wording of Mark here.

² sn The Bible makes it clear that the Law was the revelation of God at Mount Sinai. And yet study has shown that the law code’s form follows the literary pattern of covenant codes in the Late Bronze Age, notably the Hittite codes. The point of such codes is that all the covenant stipulations are appropriate because of the wonderful things that the sovereign has done for the people. God, in using a well-known literary form, was both drawing on the people’s knowledge of such to impress their duties on them, as well as putting new wine into old wineskins. The whole nature of God’s code was on a much higher level. For this general structure, see M. G. Kline, Treaty of the Great King. For the Ten Commandments specifically, see J. J. Stamm and M. E. Andrew, The Ten Commandments in Recent Research (SBT). See also some of the general articles: M. Barrett, “God’s Moral Standard: An Examination of the Decalogue,” BV 12 (1978): 34-40; C. J. H.

² sn The Greek word ἀνομία (anomia) is often translated “iniquity” or “lawlessness” and in the LXX refers particularly to transgression of the law of Moses. In Jewish thought the ideas of sin (ἁμαρτία, Jamartia) and lawlessness or iniquity (ἀνομία) were often equated because sin involved a violation of the Mosaic law and hence lawlessness. For example, Ps 51:5 LXX sets the two in parallel, and Paul in Rom 4:7 (quoting Ps 32:1) does the same. For the author, it is not violation of the Mosaic law that results in lawlessness, since he is writing to Christians. The ‘law’ for the author is the law of love, as given by Jesus in the new commandment of John 13:34-35. This is the command to love one’s brother, a major theme of 1 John and the one specific sin in the entire letter which the opponents are charged with (3:17). Since the author has already labeled the opponents “antichrists” in 2:18, it may well be that he sees in their iniquitous behavior of withdrawing from the community and refusing to love the brethren a foreshadowing of the apocalyptic iniquity of the end times (cf. 2 Thess 2:3-8). In Matt 24:11-12 Jesus foretold that false prophets would arise in the end times (cf. 1 John 4:1), that lawlessness (anomia) would increase, and that “the love of many will grow cold” (which would certainly fit the author’s portrait of the opponents here).

³ sn “My Father is working until now, and I too am working.” What is the significance of Jesus’ claim? A preliminary understanding can be obtained from John 5:18, noting the Jewish authorities’ response and the author’s comment. They sought to kill Jesus, because not only was he breaking the Sabbath, but he was also calling God his own Father, thus making himself equal with God. This must be seen in the context of the relation of God to the Sabbath rest. In the commandment (Exod 20:11) it is explained that “In six days the Lord made the heavens and the earth…and rested on the seventh day; therefore the Lord blessed the Sabbath day and made it holy.” Philo, based on the LXX translation of Exod 20:11, denied outright that God had ever ceased his creative activity. And when Rabban Gamaliel II, R. Joshua, R. Eleazar ben Azariah, and R. Akiba were in Rome, ca. a.d. 95, they gave as a rebuttal to sectarian arguments evidence that God might do as he willed in the world without breaking the Sabbath because the entire world was his private residence. So even the rabbis realized that God did not really cease to work on the Sabbath: Divine providence remained active on the Sabbath, otherwise, all nature and life would cease to exist. As regards men, divine activity was visible in two ways: Men were born and men died on the Sabbath. Since only God could give life and only God could deal with the fate of the dead in judgment, this meant God was active on the Sabbath. This seems to be the background for Jesus’ words in 5:17. He justified his work of healing on the Sabbath by reminding the Jewish authorities that they admitted God worked on the Sabbath. This explains the violence of the reaction. The Sabbath privilege was peculiar to God, and no one was equal to God. In claiming the right to work even as his Father worked, Jesus was claiming a divine prerogative. He was literally making himself equal to God, as 5:18 goes on to state explicitly for the benefit of the reader who might not have made the connection.
