Ezekiel 43:16-18

New Catholic Bible

¹⁶ The hearth was a square, twelve cubits long by twelve cubits wide. ¹⁷ The upper ledge was also a square, fourteen cubits long by fourteen cubits wide, with a rim around it a half cubit wide and a surrounding base of one cubit. The steps of the altar face the east.

¹⁸ Then he said to me: Son of man, thus says the Lord God: These are the regulations for the altar when it has been erected for the offering of holocausts upon it and for the sprinkling of blood upon it.
