Deuteronomy 27:2-4

21So it shall be on the day when you cross the Jordan to the land which the Lord your God is giving you, that you shall set up for yourself large stones and coat them with lime

3and write on them all the words of this Law, when you cross over, so that you may enter the land which the Lord your God is giving you, 2a land flowing with milk and honey, just as the Lord, the God of your fathers, 3promised you.

4So it shall be when you cross the Jordan, you shall set up these stones 4on Mount Ebal, 5as I am commanding you today, and you shall coat them with lime.
