Exodus 29:37-41

For seven days you shall make atonement for the altar and consecrate it; then the altar shall be most holy, and whatever touches the altar shall be holy.

“Now this is what you shall offer on the altar: two one-year-old lambs each day, continuously.

The one lamb you shall offer in the morning, and the other lamb you shall offer at twilight;

and there shall be a tenth of an ephah of fine flour mixed with a fourth of a hin of beaten oil, and a fourth of a hin of wine for a drink offering with one lamb.

The other lamb you shall offer at twilight, and shall offer with it the same grain offering and the same drink offering as in the morning, for a soothing aroma, an offering by fire to the Lord.
