1 Samuel 20

41 And as soon as the lad was gone, David arose from the south side of the stone, and fell on his face to the ground, and bowed himself three times: and they kissed one another, and wept one with another, until David exceeded.

42 And Jonathan said to David, Go in peace: what we have sworn, both of us, in the name of the Lord, saying, The Lord shall be between me and thee, and between my seed and thy seed for ever, shall be kept. (21:1) And he arose and departed; and Jonathan went into the city.
