2 Kings 13 is a chapter that focuses on the reign of Jehoahaz, the son of Jehu, as king of Israel. The chapter begins with a brief overview of Jehoahaz's reign, noting that he did what was evil in the sight of the Lord and that the Lord was angry with Israel. This is followed by a description of the oppression that Israel faced from the King of Syria, who had been attacking them for many years. The chapter then goes on to describe how the Lord raised up a deliverer for Israel in the form of Jehoahaz's son, Jehoash. Jehoash was able to defeat the Syrians and restore Israel's independence. The chapter ends with a brief description of Jehoash's reign and his death.
Overall, this chapter serves as a reminder of the power of God to deliver his people from their enemies. Despite the fact that Jehoahaz had done evil in the sight of the Lord, the Lord still raised up a deliverer for Israel in the form of Jehoash. This is a reminder that God is faithful to his people, even when they are unfaithful to him. It is also a reminder that God is sovereign over all things, and that he is able to bring about his will, even in the midst of difficult circumstances.
