The Lord promises that his wrath (cup) will be removed from Israel, and poured out upon their enemies. The imagery is that of the cup full of wrath removed from Israel and given (still full of wrath) over to those who oppress Israel. The final image is of the effect of the afflictors on Israel, that they have broken the soul of Israel, and trampled on it - esteemed it of no worth. Implicit in this change of direction of fury is that the Lord does recognize the worth of Israel's soul.
