1st Samuel 20:36

33 And Saul cast a javelin at him to smite him: whereby Jonathan knew that it was determined of his father to slay David.

34 So Jonathan arose from the table in fierce anger, and did eat no meat the second day of the month: for he was grieved for David, because his father had done him shame.

35 And it came to pass in the morning, that Jonathan went out into the field at the time appointed with David, and a little lad with him.

36 And he said unto his lad, Run, find out now the arrows which I shoot. And as the lad ran, he shot an arrow beyond him.

37 And when the lad was come to the place of the arrow which Jonathan had shot, Jonathan cried after the lad, and said, Is not the arrow beyond thee?

38 And Jonathan cried after the lad, Make speed, haste, stay not. And Jonathan's lad gathered up the arrows, and came to his master.

39 But the lad knew not any thing: only Jonathan and David knew the matter.
