From Faith Futures
From the commentary in [The Five Gospels]:
Like the complex in Luke 19:41-45, this group of sayings also constitutes a prophetic oracle. Luke has given it a narrative setting by introducing weeping women in v. 27 and then having Jesus respond to them: don't weep for me, weep for yourselves. Jesus then employs an analogy: in the future -- at the destruction of the city of Jerusalem -- they will congratulate those who have no children. Hos 10:8 is quoted to back up the prediction. These sentences have eschatological overtones that are reminiscent of the little apocalypse in Luke 21:5-36 and the parallels in Mark and Matthew. The Fellows of the Jesus Seminar could identify nothing in them that could be traced back to Jesus.
Luedemann [Jesus] (404):
These verses are a Christian prophecy which 'was put into the mouth of Jesus on the way to the cross' (Bultmann) here by Luke. It reinforces the anti-Judaism of the Lukan passion story further. The lamentation should not be for Jesus but for the inhabitants of Jerusalem, who will receive a harsh punishment. The lamenting women represent the Jewish people, which is a witness to the crucifixion (vv. 35,48). Verse 29, as a paraphrase of Isa. 54.1, is a kind of counterpart to 11.27. If there it was said of the mother of Jesus, 'Blesssed is the womb which bore you and the breasts which you sucked,' so here the opposite is said of the women of Jerusalem. Verse 30 takes up Hos. 10.8. Verse 31 gives the reason for the punishment coming upon Jerusslem with a proverb (cf. Prov. 11.31).
