1 Samuel 20:38-42

Then Jonathan called after the boy, “Hurry, be quick, do not stay!” And Jonathan’s boy picked up the arrow and came to his master.

But the boy was not aware of anything; only Jonathan and David knew about the matter.

Then Jonathan gave his weapons to his boy and said to him, “Go, bring them to the city.”

When the boy was gone, David got up from the south side, then he fell on his face to the ground and bowed three times. And they kissed each other and wept together, until David wept immeasurably.

Then Jonathan said to David, “Go in safety, since we have sworn to each other in the name of the Lord, saying, ‘The Lord will be between me and you, and between my descendants and your descendants forever.’ ” So David set out and went on his way, while Jonathan went into the city.
