1 Samuel 17:38-45 New Living Translation (NLT)

³⁸ Then Saul gave David his own armor—a bronze helmet and a coat of mail. ³⁹ David put it on, strapped the sword over it, and took a step or two to see what it was like, for he had never worn such things before.

“I can’t go in these,” he protested to Saul. “I’m not used to them.” So David took them off again. ⁴⁰ He picked up five smooth stones from a stream and put them into his shepherd’s bag. Then, armed only with his shepherd’s staff and sling, he started across the valley to fight the Philistine.

⁴¹ Goliath walked out toward David with his shield bearer ahead of him, ⁴² sneering in contempt at this ruddy-faced boy. ⁴³ “Am I a dog,” he roared at David, “that you come at me with a stick?” And he cursed David by the names of his gods. ⁴⁴ “Come over here, and I’ll give your flesh to the birds and wild animals!” Goliath yelled.

⁴⁵ David replied to the Philistine, “You come to me with sword, spear, and javelin, but I come to you in the name of the Lord of Heaven’s Armies—the God of the armies of Israel, whom you have defied.
