1 Samuel 17:42-46

When the Philistine looked around and saw David, he derided and disparaged him because he was [just] a young man, with a ruddy complexion, and a handsome appearance. The Philistine said to David, “Am I a dog, that you come to me with [shepherd’s] staffs?” And the Philistine cursed David by his gods. The Philistine also said to David, “Come to me, and I will give your flesh to the birds of the sky and the beasts of the field.” Then David said to the Philistine, “You come to me with a sword, a spear, and a javelin, but I come to you in the name of the LORD of hosts, the God of the armies of Israel, whom you have taunted. This day the LORD will hand you over to me, and I will strike you down and cut off your head. And I will give the corpses of the army of the Philistines this day to the birds of the sky and the wild beasts of the earth, so that all the earth may know that there is a God in Israel
