1 Samuel 20:35-39

The next morning Jonathan went out to the field to meet David as they had agreed. He had a young boy with him. Jonathan said to the boy, “Run and find the arrows I shoot.” When he ran, Jonathan shot an arrow beyond him. The boy ran to the place where Jonathan’s arrow fell, but Jonathan called, “The arrow is beyond you!” Then he shouted, “Hurry! Go quickly! Don’t stop!” The boy picked up the arrow and brought it back to his master. (The boy knew nothing about what this meant; only Jonathan and David knew.)
