Exodus 29:37-39

The Voice

³⁷ For seven days you must purify the altar and consecrate it. As a result of these rituals it will be most holy and anything that touches the altar will become holy.

³⁸ Here are the sacrifices you are to offer on the altar: every day offer two one-year-old lambs. ³⁹ Offer one lamb in the morning, and the other at twilight.
