New Revised Standard Version, Anglicised Catholic Edition

²¹ You shall also take the bull of the sin-offering, and it shall be burnt in the appointed place belonging to the temple, outside the sacred area.

²² On the second day you shall offer a male goat without blemish for a sin-offering; and the altar shall be purified, as it was purified with the bull. ²³ When you have finished purifying it, you shall offer a bull without blemish and a ram from the flock without blemish.
