Deuteronomy 27:2-4 ▼

2 And it shall be on the day that you cross the Jordan into the land which the LORD your God gives you, you shall set up large stones, and cover them with plaster;

3 And you shall write upon them all the words of this law, when you have crossed the Jordan, that you may go into the land which the LORD your God gives you, a land flowing with milk and honey, as the LORD God of your fathers has promised you.

4 Therefore when you have crossed the Jordan, you shall set up these stones, which I command you this day, on mount Gebel, and you shall cover them with plaster.
