Exodus 20:24-26

Douay-Rheims 1899 American Edition

²⁴ You shall make an altar of earth unto me, and you shall offer upon it your holocausts and peace offerings, your sheep and oxen, in every place where the memory of my name shall be: I will come to thee, and will bless thee.

²⁵ And if thou make an altar of stone unto me, thou shalt not build it of hewn stones: for if thou lift up a tool upon it, it shall be defiled.

²⁶ Thou shalt not go up by steps unto my altar, lest thy nakedness be discovered.
