Deuteronomy 27:4-6

New Living Translation

⁴ When you cross the Jordan, set up these stones at Mount Ebal and coat them with plaster, as I am commanding you today.

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.
