2 Kings 10:30
And the LORD said unto Jehu, Because thou hast done well in executing that which is right in mine eyes, and hast done unto the house of Ahab according to all that was in mine heart, thy children of the fourth generation shall sit on the throne of Israel.
And the Lord said unto Jehu,.... By a prophet, he not being one himself; and this is generally supposed, by the Jews {w}, to be Jonah the son of Amittai:
Because thou hast done well in executing that which is right in mine eyes: in rooting out the idolatry of Baal, which was right in the sight of God, and was materially a good work, though it might not be done from a good principle, nor every step taken in doing it justifiable:
and hast done unto the house of Ahab according to all that was in mine heart: that he had decreed within himself should be done, and had foretold by his prophets would be done, the doing of which was acceptable and well pleasing to him:
thy children of the fourth generation shall sit on the throne of Israel; as they did, namely, Jehoahaz, Joash, Jeroboam, and Zachariah, though the last reigned but six months, just enough to fulfil this promise.
