Deuteronomy 27:3-5

New Living Translation

³ Write this whole body of instruction on them when you cross the river to enter the land the Lord your God is giving you—a land flowing with milk and honey, just as the Lord, the God of your ancestors, promised you. 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.
