And Jehoahaz besought the Lord, and the Lord hearkened unto him: for he saw the oppression of Israel, because the king of Syria oppressed them. (2 Kings 13:4)
The Lord is a God of mercy and goodness. He is always willing to forgive when sinners repent and turn to Him. When Jehoahaz turned to God, the Lord in His kindness directed events so as to grant Israel deliverance.
