1 Samuel 17:38-40

Wycliffe Bible

³⁸ And Saul clothed David with his clothes, and he set a brazen basinet on his head, and clothed him with an habergeon.

³⁹ Therefore David was girded with his sword on his cloak, and began to assay if he might go armed; for he had not [the] custom. And David said to Saul, I may not go thus, for I have not the uses of it. And David put away (all) those [things],

⁴⁰ and he took his staff, that he had ever[more] in his hands. And he chose to him five full clear round stones, that is, hard, plain, and round, of the strand (And he chose out of the stream for himself five hard, round, plain stones); and he put those into his shepherd’s script, that he had with him; and he took a sling in his hand, and he went forth against the Philistine.
