13:9 By turning against the Lord who only desired to help them (cf. v. 4), the Israelites had done something that would result in their own destruction. How ironic it was that Israel's helper would become her destroyer!
13:10 The people had formerly asked their leaders to give them a king like all the other nations. They hoped that their king and his princes would provide deliverance for them. God had given them kings, first Saul (1 Sam. 8:4-9; 12:12) and more recently the kings of Israel that were not of David's line but were kings of the people's own choosing (1 Kings 12:16-20). Yet all these kings had proved ineffective in saving the Israelites. Only Yahweh was their savior (v. 4).
13:11 God conceded to His people's request for a king, but it made Him angry because it expressed their reluctance to trust and obey Him. When Saul proved ineffective, since He did not trust in Yahweh, the Lord removed him, which also made Him angry. The Lord would also remove all the Ephraimite kings because they followed the pattern of Saul. The sins and bad times that all these kings' reigns brought on Israel were unnecessary and displeasing to the Lord who wanted His people to enjoy peace and prosperity.
