1 Samuel 20:41-42 NIV

[41] After the boy had gone, David got up from the south side of the stone and bowed down before Jonathan three times, with his face to the ground. Then they kissed each other and wept together—but David wept the most. [42] Jonathan said to David, “Go in peace, for we have sworn friendship with each other in the name of the Lord, saying, ‘The LORD is witness between you and me, and between your descendants and my descendants forever.’ ” Then David left, and Jonathan went back to the town.
