Deuteronomy 27:2–8

²And it shall be on the day when ye shall 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 art passed over; that thou mayest go in unto 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 are passed over the Jordan, that ye shall set up these stones, which I command you this day, in mount Ebal, and thou shalt plaster them with plaster. ⁵And there shalt thou build an altar unto Jehovah thy God, an altar of stones: thou shalt lift up no iron tool upon them. ⁶Thou shalt build the altar of Jehovah thy God of unhewn stones; and thou shalt offer burnt-offerings thereon unto Jehovah thy God: ⁷and thou shalt sacrifice peace-offerings, and shalt eat there; and thou shalt rejoice before Jehovah thy God. ⁸And thou shalt write upon the stones all the words of this law very plainly.
