1 Samuel 13:20-22

New Century Version

²⁰ So all the Israelites had to go down to the Philistines to have their plows, hoes, axes, and sickles sharpened. ²¹ The Philistine blacksmiths charged about one-fourth of an ounce of silver for sharpening plows and hoes. And they charged one-eighth of an ounce of silver for sharpening picks, axes, and the sticks used to guide oxen.

²² So when the battle came, the soldiers with Saul and Jonathan had no swords or spears. Only Saul and his son Jonathan had them.
