1 Samuel 29:5

[Is] not this David, of whom they sang one to another in
dances
Long ago:

saying, Saul slew his thousands, and David his ten thousands;
so that he is an old sworn enemy of ours; and the more valiant and victorious he has been, the less is he to be trusted, see ( 1 Samuel 18:7 ) ( 21:11 ) .
