Exodus

²¹And the people stood afar off, and Moses drew near unto the thick darkness where God was. ²²And the Lord said unto Moses, Thus thou shalt say unto the children of Israel, Ye yourselves have seen that I have talked with you from heaven. ²³Ye shall not make other gods with me; gods of silver, or gods of gold, ye shall not make unto you. ²⁴An altar of earth thou shalt make unto me, and shalt sacrifice thereon thy burnt offerings, and thy peace offerings, thy sheep, and thine oxen: in every place where I record my name I will come unto thee and I will bless thee. ²⁵And if thou make me an altar of stone, thou shalt not build it of hewn stones: for if thou lift up thy tool upon it, thou hast polluted it. ²⁶Neither shalt thou go up by steps unto mine altar, that thy nakedness be not discovered thereon.
