Exodus 20:23 DBY

²¹  And the people stood afar off, and Moses drew near to the obscurity where God was.

²²  And Jehovah said to Moses, Thus shalt thou say to the children of Israel: Ye have seen that I have spoken with you from the heavens.

²³  Ye shall not make beside me gods of silver, and ye shall not make to you gods of gold.

²⁴  An altar of earth shalt thou make unto me, and shalt sacrifice on it thy burnt-offerings, and thy peace-offerings, thy sheep and thine oxen: in all places where I shall make my name to be remembered, I will come unto thee, and bless thee.

²⁵  And if thou make me an altar of stone, thou shalt not build it of hewn stone; for if thou lift up thy sharp tool upon it, thou hast profaned it.
