Hosea 7:3

They make the king glad - They pleased Jeroboam by coming readily into his measures, and heartily joining with him in his idolatry. And they professed to be perfectly happy in their change, and to be greatly advantaged by their new gods; and that the religion of the state now was better than that of Jehovah. Thus, they made all their rulers, "glad with their lies."

They make the king glad with their wickedness - Wicked sovereigns and a wicked people are a curse to each other, each encouraging the other in sin. Their king, being wicked, had pleasure in their wickedness; and they, seeing him to be pleased by it, set themselves the more, to do what was evil, and to amuse him with accounts of their sins. Sin is in itself so shameful, that even the great cannot, by themselves, sustain themselves in it, without others to flatter them. A good and serious man is a reproach to them. And so, the sinful great corrupt others, both as aiding them in their debaucheries, and in order not to be reproached by their virtues, and because the sinner has a corrupt pleasure and excitement in hearing of tales of sin, as the good joy to hear of good. Whence Paul says, "who, knowing the judgment of God that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them" Romans 1:32.

But whereas, they all, kings, princes, and people, thus agreed and conspired in sin, and the sin of the great is the rarest destructive, the prophet here upbraids the people most for this common sin, apparently because they were free from the greater temptations of the great, and so their sin was the more willful. "An unhappy complaisance was the ruling character of Israel. It preferred its kings to God. Conscience was versatile, accommodating. Whatever was authorized by those in power, was approved." Ahab added the worship of Baal to that of the calves; Jehu confined himself to the sin of Jeroboam. The people acquiesced in the legalized sin. Much as if now, marriages, which by God's law are incest, or remarriages of the divorced, which our Lord pronounces adultery, were to be held allowable, because man's law ceases to annex any penalty to them.

7:3 They - The courtiers in particular make it their work to invent pleasing wickedness, and to acquaint the king with it.With their lies - With false accusations against the innocent.
