1 Samuel 17:39-41

Modern English Version

³⁹ David secured his sword to his armor and tried to walk, but he was not used to it, for he had not tested them.

And David said to Saul, “I cannot walk with these, for I have not tested them.” So David took them off. ⁴⁰ He took his staff in his hand and chose for himself five smooth stones out of the brook. And he put them in his shepherd’s bag, even in a pouch. And his sling was in his hand. Then he drew near to the Philistine.

⁴¹ The Philistine came walking and drew near to David, and the man bearing the shield went before him.
