The Lord repented; this, spoke after the manner of man, is to be understood as becomes the immutability and omniscience of God; what a man when he repenteth doth, desisting front the thing, so God, desisting or suspending his own act, doth tell us he repenteth. It shall not be: this explains the former; that sore famine like to be caused by these locusts came not, Amos prevailed by prayer, and the judgment was diverted.
