2 Kings 13:4

Jehoahaz besought the Lord, and the Lord hearkened unto him Just as in the case of punishment God does not always visit at once, even though an Ahab have sold himself to work wickedness, so in the case of mercy, the intervention of Jehovah is postponed to another generation. The Syrians are allowed to oppress Israel all the days of Jehoahaz, though we are told that his prayer had been heard. In the days of Jehoash, the next successor, some alleviation was afforded by the victories of that king over Benhadad (2 Kings 13:25), but it was not, as it seems, till the following generation that the full answer to the prayer came.
