Hosea 1:4

Hos. 1:4. "For yet a little while, and I will avenge the blood of Israel upon the house of Jehu." This prophecy was given in the days of Jeroboam, a king of the house of Jehu, not long before the destruction of that house; for Zechariah, Jeroboam's son and successor, was the last that reigned of that family, and he reigned but six months. Jehu's killing all that were of the house of Ahab, was both rewarded and punished; it was rewarded, because as to the matter of it, it was agreeable to God's command; (see 2 Kings 10:30); but it was done in a wicked manner. He did not do it so much from a spirit of obedience as from an aim at his own advancement; for he little regarded God's honor in it, as afterwards plainly appeared by his idolatry, the very sin for which he was bid to kill Ahab and destroy his family. God saw that he did it with a murderous heart, and so punishes it by the overthrow of his family. As Jehu with a murderous heart slew Ahab and all his family, so shall the posterity of Jehu be slain, and his family be overthrown in their turn. So the house of Baasha was rooted out, because he did the like to Jeroboam, 1 Kings 16:7, because Jehu performed the matter of God's command, he was rewarded by continuing the crown of Israel in his family unto the fourth generation, but because he did it in a wicked manner, as his after-behavior manifested, therefore it was continued no longer, but then taken away. His doing the matter of his duty was rewarded, but his doing it in a murderous manner was punished: which two things are not at all inconsistent.
