Isaiah 51:18-20

18-20. There is none to guide her There is none like Messiah to guide and lead. The sons of Jerusalem namely, the priests and prophets have lost character, hence ability spiritually to guide. Two things, or two classes of evils, have happened to her: destruction ( waste) and desolation famine and the sword. The state suffers the first, the people the second. Where are the pitying ones to give thee aid? Or, by whom shall I, Messiah, render thee aid? See Lamentations 2:13. The twentieth verse is a little difficult of interpretation. This whole passage is in the tone of sore lamentation. The twentieth verse, especially, dramatically exhibits people after nightfall flung out of the city (Babylon, we will suppose) for safety. But the gates become shut, and they are caught just as the hunter captures wild antelopes (such is the meaning) in a net which he fixes in the field, and into which he drives his prey. All this is the judgment of God upon Jerusalem.
