Deuteronomy 27:2–8

²And it shall be on the day when ye pass over the Jordan unto the land which Jehovah thy God giveth thee, that thou shalt set thee up great stones, and plaster them with plaster: ³and thou shalt write upon them all the words of this law, when thou goest over that thou mayest enter into the land which Jehovah thy God giveth thee, a land flowing with milk and honey, as Jehovah the God of thy fathers hath promised thee. ⁴And it shall be when ye go over the Jordan, that ye shall set up these stones, as I command you this day, on mount Ebal, and thou shalt plaster them with plaster. ⁵And there shalt thou build an altar to Jehovah thy God, an altar of stones; thou shalt not lift up an iron tool upon them; ⁶of whole stones shalt thou build the altar of Jehovah thy God; and thou shalt offer up burnt-offerings thereon to Jehovah thy God. ⁷And thou shalt sacrifice peace-offerings, and shalt eat there, and rejoice before Jehovah thy God. ⁸And thou shalt write upon the stones all the words of this law very plainly.
