1 Samuel 13:16 (KJV)

And Samuel said, What hast thou done? And Saul said, Because I saw that the people were scattered from me, and that thou camest not within the days appointed, and that the Philistines gathered themselves together at Michmash;

Therefore said I, The Philistines will come down now upon me to Gilgal, and I have not made supplication unto the LORD: I forced myself therefore, and offered a burnt offering.

And Samuel said to Saul, Thou hast done foolishly: thou hast not kept the commandment of the LORD thy God, which he commanded thee: for now would the LORD have established thy kingdom upon Israel for ever.

But now thy kingdom shall not continue: the LORD hath sought him a man after his own heart, and the LORD hath commanded him to be captain over his people, because thou hast not kept that which the LORD commanded thee.

And Samuel arose, and gat him up from Gilgal unto Gibeah of Benjamin. And Saul numbered the people that were present with him, about six hundred men.

And the spoilers came out of the camp of the Philistines in three companies: one company turned unto the way that leadeth to Ophrah, unto the land of Shual:

And another company turned the way to Bethhoron: and another company turned to the way of the border that looketh to the valley of Zeboim toward the wilderness.

Now there was no smith found throughout all the land of Israel: for the Philistines said, Lest the Hebrews make them swords or spears:

But all the Israelites went down to the Philistines, to sharpen every man his share, and his coulter, and his axe, and his mattock.

Yet they had a file for the mattocks, and for the coulters, and for the forks, and for the axes, and to sharpen the goads.
