1 Samuel 17:37-39 Darby Translation (DARBY)
37 And David said, Jehovah who delivered me out of the paw of the lion and out of the paw of the bear, he will deliver me out of the hand of this Philistine. And Saul said to David, Go, and Jehovah be with thee.
38 And Saul clothed David with his dress, and put a helmet of bronze upon his head, and clothed him with a corselet.
39 And David girded his sword upon his dress, and endeavoured to go; for he had not yet tried [it]. And David said to Saul, I cannot go in these; for I have never tried [them]. And David put them off him.
