³ sn The expression found favor is a Semitism, common in the OT (Gen 6:8; 18:3; 43:14; 2 Sam 15:25). God has chosen to act on this person’s behalf.

¹ tn Heb “uncleanness.” The noun טֻמְאָה (tum’ah, “uncleanness”) refers in general to the state of ritual uncleanness and specifically to (1) sexual uncleanness (Num 5:19); (2) filthy mass (Ezek 24:11; 2 Chr 29:16); (3) ritual uncleanness (Lev 16:16, 19; Ezek 22:15; 24:13; 36:25, 29; 39:24; Zech 13:2); (4) menstrual uncleanness (Lev 15:25, 26, 30; 18:19; Ezek 36:17); (5) polluted meat (Judg 13:7, 14). Here, Jerusalem is personified as a woman whose menstrual uncleanness has soiled even her own clothes; this is a picture of the consequences of the sin of Jerusalem: uncleanness = her sin, and soiling her own clothes = consequences of sin. The poet may also be mixing metaphors allowing various images (of shame) to circulate in the hearer’s mind, including rape and public exposure. By not again mentioning sin directly (a topic relatively infrequent in this book), the poet lays a general acknowledgment of sin in 1:8 alongside an exceptionally vivid picture of the horrific circumstances which have come to be. It is no simplistic explanation that sin merits such inhumane treatment. Instead 1:9 insists that no matter the legal implications of being guilty, the Lord should be motivated to aid Jerusalem (and therefore her people) because her obscene reality is so revolting.

³ sn This action of Jesus on behalf of his disciples is interpreted by the author as a fulfillment of Jesus’ own words: “I have not lost a single one of those whom you gave me.” Here it is Jesus’ own words, rather than the OT scriptures, which are quoted. This same formula will be used by the author again of Jesus’ words in 18:32, but the verb is used elsewhere in the Fourth Gospel to describe the NT fulfillment of OT passages (12:38, 13:18, 15:25, 17:12, 19:24, and 19:36). It is a bit difficult to determine the exact referent, since the words of Jesus quoted in this verse are not an exact reproduction of a saying of Jesus elsewhere in John’s Gospel. Although some have identified the saying with John 6:39, the closest parallel is in 17:12, where the betrayer, Judas, is specifically excluded. The words quoted here in 18:9 appear to be a free rendition of 17:12.
