1 Samuel 20

41 And 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 regained control.

42 And Jonathan said to David, Go in peace, since as we have sworn both of us in the name of the LORD, saying, The LORD be between me and you, and between my descendants and your descendants forever. And he arose and departed: and Jonathan went into the city.
