I Samuel 14:17

17 Then Saul said to the men who were with him, "Muster the forces and see who has left us." When they did, it was Jonathan and his armor-bearer who were not there.

17 Then Saul said to the people who were with him, Let everyone be numbered and let us see who has gone from us. And when they had been numbered, it was seen that Jonathan and his servant were not there.
