1 Samuel 17:37-39 Common English Bible (CEB)
37 “The Lord,” David added, “who rescued me from the power of both lions and bears, will rescue me from the power of this Philistine.”
“Go!” Saul replied to David. “And may the Lord be with you!”
38 Then Saul dressed David in his own gear, putting a coat of armor on him and a bronze helmet on his head. 39 David strapped his sword on over the armor, but he couldn’t walk around well because he’d never tried it before. “I can’t walk in this,” David told Saul, “because I’ve never tried it before.” So he took them off.
