1 Samuel 24:8

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 1 Samuel 20:41 .
