Deuteronomy 27:4

Soon as you have crossed the Jordan—when you are come to the land which the Lord the God of thy fathers giveth thee—a land flowing with milk and honey, as the Lord the God of thy fathers promised thee, you shall, immediately after your crossing the Jordan, set up these stones, which I this day command thee, at mount Garizin, and thou shalt plaster them with mortar,

And it shall be as soon as ye are gone over Jordan, ye shall set up these stones, which I command thee this day, on mount Gæbal, and thou shalt plaster them with plaster.
