Joshua 8:30-32

Then Joshua built an altar to the LORD, the God of Israel, on Mount Ebal. He followed the commands that Moses the LORD’s servant had written in the Book of Instruction: “Make me an altar from stones that are uncut and have not been shaped with iron tools.” Then on the altar they presented burnt offerings and peace offerings to the LORD. And as the Israelites watched, Joshua copied onto the stones of the altar the instructions Moses had given them.
