Hosea 10:15

So shall Beth-el do unto you - This shall be the consequence of your idolatry.

In a morning shall the king of Israel utterly be cut off - Suddenly, unexpectedly. Hoshea, the king of Israel, shall be cut off by the Assyrians. There are some allusions to facts in this chapter, which cannot be easily verified, as we have not sufficient acquaintance with the history of those times.

So shall Bethel do unto you - God was the judge, who condemned them so to suffer from the enemy. The Assyrian was the instrument of the wrath of God. But, in order to point out the moral government of God, the prophet says, neither that God did it, nor that the Assyrian did it, but Bethel, once "the house of God," now the place where they dishonored God, "because of your great wickedness," literally, "the wickedness of your wickedness." In their wickedness itself, there was an essence of wickedness, malice within malice.

In a morning shall the king of Israel be cut off - Hoshea was cut off finally, leaving neither root nor branch. His kingdom perished; he left no memorial. Like the morning, he seemed to dawn on the troubles of his people: he sinned against God: and "in a morning," the kingdom, in "the multitude of" whose "mighty men" he trusted, "was cut off" forever.

10:15 Beth-el - The idolatry committed there. Do - Procure all this evil against you. In a morning - Possibly the Assyrians might assault the city towards morning and master it.
