Exodus 29:37

34 If anything of the flesh of the consecration, or of the bread, remains to the morning, then you shall burn the remainder with fire: it shall not be eaten, because it is holy.

35 "Thus shall you do to Aaron, and to his sons, according to all that I have commanded you. Seven days shall you consecrate them.

36 Every day shall you offer the bull of sin-offering for atonement: and you shall cleanse the altar, when you make atonement for it; and you shall anoint it, to sanctify it.

37 Seven days you shall make atonement for the altar, and sanctify it: and the altar shall be most holy; whatever touches the altar shall be holy.

38 "Now this is that which you shall offer on the altar: two lambs a year old day by day continually.

39 The one lamb you shall offer in the morning; and the other lamb you shall offer at evening:

40 and with the one lamb a tenth part of an ephah of fine flour mixed with the fourth part of a hin of beaten oil, and the fourth part of a hin of wine for a drink-offering.
