1 Samuel 17:37-39 Complete Jewish Bible (CJB)
37 Then David said, “Adonai, who rescued me from the paw of the lion and from the paw of the bear, will rescue me from the paw of this P’lishti!” Sha’ul said to David, “Go; may Adonai be with you.”
38 Sha’ul dressed David in his own armor — he put a bronze helmet on his head and gave him armor plate to wear. 39 David buckled his sword on his armor and tried to walk, but he wasn’t used to such equipment. David said to Sha’ul, “I can’t move wearing these things, because I’m not used to them.” So David took them off.
