Jonathan and his armor-bearer devised a plan to test if God would help a few men defeat many Philistines. They showed themselves to the Philistine outpost and were challenged to come up, taking this as a sign from God. Jonathan and his armor-bearer climbed up and started killing Philistines, causing panic among their whole army. The Israelites who had been hiding joined in, and God helped deliver Israel from the Philistines that day.
