5. “Then build an altar there to the lord your God, using natural, uncut stones. You must not shape the stones with an iron tool.

6. Build the altar of uncut stones, and use it to offer burnt offerings to the lord your God.

7. Also sacrifice peace offerings on it, and celebrate by feasting there before the lord your God.

8. You must clearly write all these instructions on the stones coated with plaster.”
