Joshua 8:31
just as Moses the servant of the LORD had commanded the Israelites. He built it according to what is written in the Book of the Law of Moses: “an altar of uncut stones on which no iron tool has been used.” And on it they offered burnt offerings to the LORD, and they sacrificed peace offerings.
1 Kings 6:7
The temple was constructed using finished stones cut at the quarry, so that no hammer or chisel or any other iron tool was heard in the temple while it was being built.
