Exodus 29:38

35 All these things you are to do to Aaron and his sons as I have given you orders: for seven days the work of making them priests is to go on.

36 Every day an ox is to be offered as a sin-offering, to take away sins: and by this offering on it, you will make the altar clean from sin; and you are to put oil on it and make it holy.

37 For seven days you are to make offerings for the altar and make it holy, so that it may become completely holy, and anything touching it will become holy.

38 Now this is the offering which you are to make on the altar: two lambs in their first year, every day regularly.

39 One lamb is to be offered in the morning and the other in the evening:

40 And with the one lamb, a tenth part of an ephah of the best meal, mixed with a fourth part of a hin of clear oil; and the fourth part of a hin of wine for a drink offering.

41 And the other lamb is to be offered in the evening, and with it the same meal offering and drink offering, for a sweet smell, an offering made by fire to the Lord.
