Numbers 28:3-6

3You will say to them, ‘This is the offering made by fire which you must offer to the Lord: two unblemished lambs one year old each day for a continual burnt offering.

4The first lamb you must offer in the morning, and the second lamb you must offer in the late afternoon,

5with one-tenth of an ephah of finely ground flour as a grain offering mixed with one quarter of a hin of pressed olive oil.

6It is a continual burnt offering that was instituted on Mount Sinai as a pleasing aroma, an offering made by fire to the Lord.
