1 Samuel 14:1-2

14:1 Then one day Jonathan son of Saul said to his armor bearer, “Come on, let’s go over to the Philistine garrison that is opposite us.” But he did not let his father know.

14:2 Now Saul was sitting under a pomegranate tree in Migron, on the outskirts of Gibeah. The army that was with him numbered about six hundred men.
