When Saul became king over Israel, he fought against all his enemies on every side against Moab, the Ammonites, Edom, the kings of Zobah, and the Philistines. Everywhere he turned he was victorious.

But they forgot the LORD their God, so he handed them over to the domination of Sisera, the commander of the army of Hazor, and into domination by the Philistines and by the king of Moab, and Israel fought against them.

If you fear the LORD, serve him, obey him, and don't rebel against the commandment of the LORD, then both you and the king who rules over you will truly follow the LORD your God.
