1 Samuel 24:6-8

King James Version

⁶ And he said unto his men, The Lord forbid that I should do this thing unto my master, the Lord's anointed, to stretch forth mine hand against him, seeing he is the anointed of the Lord.

⁷ So David stayed his servants with these words, and suffered them not to rise against Saul. But Saul rose up out of the cave, and went on his way.

⁸ David also arose afterward, and went out of the cave, and cried after Saul, saying, My lord the king. And when Saul looked behind him, David stooped with his face to the earth, and bowed himself.
