1 Samuel 14:15-19
English Standard Version
16And the watchmen of Saul in Gibeah of Benjamin looked, and behold, the multitude was dispersing here and there.
17Then Saul said to the people who were with him, "Count and see who has gone from us." And when they had counted, behold, Jonathan and his armor-bearer were not there.
18So Saul said to Ahijah, "Bring the ark of God here." For the ark of God went at that time with the people of Israel.
19Now while Saul was talking to the priest, the tumult in the camp of the Philistines increased more and more. So Saul said to the priest, "Withdraw your hand."
