Numbers 28:4-8

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

also a tenth of an ephah of fine flour as a grain offering, mixed with a fourth of a hin of pure oil.

It is a continual burnt offering which was ordained on Mount Sinai as a soothing aroma, an offering by fire to the Lord.

Then the drink offering with it shall be a fourth of a hin for each lamb; in the Holy Place pour out a drink offering of strong drink to the Lord.

The other lamb you shall offer at twilight; as the grain offering of the morning and as its drink offering, you shall offer it, an offering by fire, a soothing aroma to the Lord.
