As Israel was preparing for battle against the Philistines, Jonathan and his armor bearer decided to investigate the Philistine camp to see if God would favor them in launching an attack. Jonathan trusted God, and God used Jonathan and his servant to conquer the entire camp. But Saul, wanting to seize the momentum, made the Israelites under his camp vow not to eat anything until the rest of the Philistines had been driven out. Knowing nothing of this vow, Jonathan disobeyed his father, who would have killed him if not for the people of Israel who interceded.
