1 Samuel 20:36

Saul cast his spear at him to strike him. By this Jonathan knew that his father was determined to put David to death.

So Jonathan arose from the table in fierce anger, and ate no food the second day of the month; for he was grieved for David, because his father had treated him shamefully.

In the morning, Jonathan went out into the field at the time appointed with David, and a little boy with him.

When the boy had come to the place of the arrow which Jonathan had shot, Jonathan cried after the boy, and said, “Isn’t the arrow beyond you?”

Jonathan cried after the boy, “Go fast! Hurry! Don’t delay!” Jonathan’s boy gathered up the arrows, and came to his master.

But the boy didn’t know anything. Only Jonathan and David knew the matter.
