1 Samuel 17:32-40

32David said to Saul, “Don’t let anyone be discouraged. Your servant will go and fight this Philistine!”

33But Saul replied to David, “You aren’t able to go against this Philistine and fight him! You’re just a boy! He has been a warrior from his youth!”

34David replied to Saul, “Your servant has been a shepherd for his father’s flock. Whenever a lion or bear would come and carry off a sheep from the flock,

35I would go out after it, strike it down, and rescue the sheep from its mouth. If it rose up against me, I would grab it by its jaw, strike it, and kill it.

36Your servant has struck down both the lion and the bear. This uncircumcised Philistine will be just like one of them. For he has defied the armies of the living God!”

37David went on to say, “The Lord who delivered me from the lion and the bear will also deliver me from the hand of this Philistine!” Then Saul said to David, “Go! The Lord will be with you.”

38Then Saul clothed David with his own fighting attire and put a bronze helmet on his head. He also put body armor on him.

39David strapped on his sword over his fighting attire and tried to walk around, but he was not used to them. David said to Saul, “I can’t walk in these things, for I’m not used to them.” So David removed them.

40He took his staff in his hand, picked out five smooth stones from the stream, placed them in the pouch of his shepherd’s bag, took his sling in hand, and approached the Philistine.
