Adam Clarke on Hosea 11:9

I will not execute - Here is the issue of this conflict in the Divine mind. Mercy triumphs over Judgment; Ephraim shall be spared. He is God, and not man. He cannot be affected by human caprices. They are now penitent, and implore mercy; he will not, as man would do, punish them for former offenses, when they have fallen into his hand. The holy place is in Ephraim, and God is in this holy place; and he will not go into the cities, as he did into Sodom and Gomorrah, to destroy them. Judgment is his strange work. How exceedingly affecting are these two verses!
