Exodus 29:37-39

Darby Translation

³⁷ Seven days shalt thou make atonement for the altar and hallow it; and the altar shall be most holy: whatever toucheth the altar shall be holy.

³⁸ And this is what thou shalt offer upon the altar—two lambs of the first year, day by day continually.

³⁹ The one lamb thou shalt offer in the morning; and the other lamb thou shalt offer between the two evenings.
