1 Samuel 20:40-42

40And Jonathan gave his weapons unto his lad, and said unto him, Go, carry them to the city. 41And as soon as the lad was gone, David arose out of a place toward the South, 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. 42And Jonathan said to David, Go in peace, forasmuch as we have sworn both of us in the name of Jehovah, saying, Jehovah shall be between me and thee, and between my seed and thy seed, for ever. And he arose and departed: and Jonathan went into the city.
