David said, [Wait a minute, don't reject me so fast. He said,] One day when I was watching my father's sheep, a lion and a bear came out and grabbed a sheep and began to drag them off. And I grabbed the sheep out of the lion's mouth: so he turned on me, and I took him by the beard, and I killed him. And I also killed the bear: and the God who delivered the lion and the bear into my hands will deliver also this uncircumcised Philistine. So Saul said, Well give you a try. Here take this helmet and this armour plate, [and so forth] and so they put this armour on David and the helmet, [And he's probably just a little kid and the helmet probably came down over his ears, and you know the armour plate's so heavy] He said, If you don't mind, I haven't tested this stuff. I don't think I better use this. I'll just go out as I am. And so David headed toward the giant ( 1 Samuel 17:34-40 ).
