1 Samuel 24:8
Ver. 8. David also arose afterward,.... After Saul was gone:
and went out of the cave; where he had been all the time that Saul had been in it:
and cried after Saul: with a loud voice: my lord the king; by which titles Saul would know that he was called unto:
and when Saul looked behind him; to see who it was that called unto him:
David stooped with his face to the earth, and bowed himself: giving reverence and honour to him as a king; See Gill on "1Sa 20:41".
