Only the Philistines could sharpen iron tools. So if the Israelites needed to sharpen their plows, hoes, axes or sickles, they had to go to the Philistines.
Josiah did the same for the towns in the areas of Manasseh, Ephraim, Simeon, and all the way to Naphtali. He did the same for the ruins near all those towns. {\cf2\super [425]}
None of the people of Israel could make things from iron. There weren’t any blacksmiths [121] in Israel. The Philistines did not teach the Israelites how to make things from iron because the Philistines were afraid the Israelites would make iron swords and spears.
The Philistine blacksmiths charged 1/3 ounce [122] {of silver} for sharpening plows and hoes. And they charged 1/6 ounce [123] {of silver} for sharpening picks, axes and the iron tip on oxgoads. [124]
