In the seventh year Jehoiada sent and fetched the captains over hundreds of the Carites and of the guard, and brought them to him into the house of Yahweh; and he made a covenant with them, and took an oath of them in the house of Yahweh, and showed them the king's son.
In the seventh year of Jehu began Jehoash to reign; and he reigned forty years in Jerusalem: and his mother's name was Zibiah of Beersheba.
This was the word of Yahweh which he spoke to Jehu, saying, "Your sons to the fourth generation shall sit on the throne of Israel." So it came to pass.
