1 Samuel 20:41-42

And as soon as the lad was gone, David arose out of a place toward the Negev and fell on his face to the ground and bowed himself three times, and they kissed one another and wept one with another, although David exceeded. And Jonathan said to David, Go in peace, forasmuch as we have sworn both of us in the name of the LORD, saying, The , saying, The LORD be between me and thee and between my seed and thy seed for ever. And he arose and departed, and Jonathan entered into the city.
