Text -- Luke 17:1-6 (NET)

Sin, Forgiveness, Faith, and Service

17:1 Jesus said to his disciples, “Stumbling blocks are sure to come, but woe to the one through whom they come! 17:2 It would be better for him to have a millstone tied around his neck and be thrown into the sea than for him to cause one of these little ones to sin. 17:3 Watch yourselves! If your brother sins, rebuke him. If he repents, forgive him. 17:4 Even if he sins against you seven times in a day, and seven times returns to you saying, ‘I repent,’ you must forgive him.” 17:5 The apostles said to the Lord, “Increase our faith!” 17:6 So the Lord replied, “If you had faith the size of a mustard seed, you could say to this black mulberry tree, ‘Be pulled out by the roots and planted in the sea,’ and it would obey you.

Commentary -- Verse Notes / Footnotes

NET Notes: Luk 17:1

¹ tn Grk “He”; the referent (Jesus) has been specified in the translation for clarity. Here δέ (de) has not been translated.

² sn See Luke 6:24-26.

NET Notes: Luk 17:2

¹ tn This term refers to the heavy upper stone of a grinding mill (L&N 7.70; BDAG 660 s.v. μυλικός).

sn The punishment of drowning with a heavy weight attached is extremely gruesome and reflects Jesus’ views concerning those who cause others who believe in him to sin.

² tn Grk “if a millstone were tied…and he were thrown.” The conditional construction in Greek has been translated by English infinitives: “to have… and be thrown.”

³ tn Or “to stumble.” This verb, σκανδαλίσῃ (skandalish), has the same root as the noun σκάνδαλον (skandalon) in 17:1, translated “stumbling blocks”; this wordplay is difficult to reproduce in English. It is possible that the primary cause of offense here would be leading disciples (“little ones”) astray in a similar fashion.

NET Notes: Luk 17:3

¹ tn It is difficult to know if this looks back or forward or both. The warning suggests it looks back. For this verb, see Luke 8:18; 12:1, 15; 20:46; 21:8, 34. The present imperative reflects an ongoing spirit of watchfulness.

² tn Both the “if” clause in this verse and the “if” clause in v. 4 are third class conditions in Greek.

³ tn Here the term “brother” means “fellow believer” or “fellow Christian” (cf. BDAG 18 s.v. ἀδελφός 2.a, contra BDAG 19 s.v. 2.c), but with a familial connotation. It refers equally to men, women, or children. However, because of the familial connotations, “brother” has been retained in the translation here in preference to the more generic “fellow believer” (“fellow Christian” would be anachronistic in this context).

⁴ tn Grk “And if.” Here καί (kai) has not been translated because of differences between Greek and English style.

NET Notes: Luk 17:4

¹ sn You must forgive him. Forgiveness is to be readily given and not withheld. In a community that is to have restored relationships, grudges are not beneficial.

NET Notes: Luk 17:5

¹ tn Grk “And the.” Here καί (kai) has not been translated because of differences between Greek and English style.

² sn The request of the apostles, “Increase our faith,” is not a request for a gift of faith, but a request to increase the depth of their faith.

NET Notes: Luk 17:6

¹ tn Here δέ (de) has been translated as “so” to indicate the implied result of previous action(s) in the narrative.

² tn Grk “said.”

³ tn This is a mixed condition, with ἄν (an) in the apodosis.

⁴ tn Grk “faith as,” “faith like.”

⁵ sn A black mulberry tree is a deciduous fruit tree that grows about 20 ft (6 m) tall and has black juicy berries. This tree has an extensive root system, so to pull it up would be a major operation.

⁶ tn The passives here (ἐκριζώθητι and φυτεύθητι, ekrizwqhti and futeuqhti) are probably a circumlocution for God performing the action (the so-called divine passive, see ExSyn 437-38). The issue is not the amount of faith (which in the example is only very tiny), but its presence, which can accomplish impossible things. To cause a tree to be uprooted and planted in the sea is impossible. The expression is a rhetorical idiom. It is like saying a camel can go through the eye of a needle (Luke 18:25).

⁷ tn The verb is aorist, though it looks at a future event, another rhetorical touch to communicate certainty of the effect of faith.
