Numbers 28:3-6

31And you shall say to them, ‘This is the offering by fire which you shall offer to the Lord: two male lambs one year old without defect as a continual burnt offering every day.

4You shall offer the one lamb in the morning, and the other lamb you shall offer 2at twilight;

5also 3a tenth of an ephah of fine flour as a 4grain offering, mixed with a fourth of a 5hin of pure oil.

6It is a continual burnt offering which was ordained on Mount Sinai as a soothing aroma, an offering by fire to the Lord.
