1 Samuel 17:38

34David said to Saul, “Your servant was keeping his father’s sheep; and when a lion or a bear came and took a lamb out of the flock,

35I went out after him, struck him, and rescued it out of his mouth. When he arose against me, I caught him by his beard, struck him, and killed him.

36Your servant struck both the lion and the bear. This uncircumcised Philistine shall be as one of them, since he has defied the armies of the living God.”

37David said, “The LORD, who delivered me out of the paw of the lion and out of the paw of the bear, will deliver me out of the hand of this Philistine.” Saul said to David, “Go! The LORD will be with you.”

38Saul dressed David with his clothing. He put a helmet of bronze on his head, and he clad him with a coat of mail.

39David strapped his sword on his clothing and he tried to move, for he had not tested it. David said to Saul, “I can’t go with these, for I have not tested them.” Then David took them off.

40He took his staff in his hand, and chose for himself five smooth stones out of the brook, and put them in the pouch of his shepherd’s bag which he had. His sling was in his hand; and he came near to the Philistine.

41The Philistine walked and came near to David; and the man who bore the shield went before him.

42When the Philistine looked around and saw David, he disdained him; for he was but a youth, and ruddy, and had a good looking face.
