Exodus 20:24 ASV

²²  And Jehovah said unto Moses, Thus thou shalt say unto the children of Israel, Ye yourselves have seen that I have talked with you from heaven.

²³  Ye shall not make 'other gods' with me; gods of silver, or gods of gold, ye shall not make unto you.

²⁴  An 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.

²⁵  And 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.

²⁶  Neither shalt thou go up by steps unto mine altar, that thy nakedness be not uncovered thereon.
