Exodus 20:23-25

New Revised Standard Version, Anglicised

²³ You shall not make gods of silver alongside me, nor shall you make for yourselves gods of gold. ²⁴ You need make for me only an altar of earth and sacrifice on it your burnt-offerings and your offerings of well-being, your sheep and your oxen; in every place where I cause my name to be remembered I will come to you and bless you. ²⁵ But if you make for me an altar of stone, do not build it of hewn stones; for if you use a chisel upon it you profane it.
