Leviticus 6:20-25

²⁰“This is the offering of Aaron and of his sons, which they will offer to Yahweh on the day when each son is anointed: a tenth part of an ephah of fine flour as a regular grain offering, half of it in the morning and half of it in the evening.

²¹It will be made with oil in a baking pan. When it is soaked, you will bring it in. In baked pieces you will offer the grain offering to produce a sweet aroma for Yahweh.

²²The son of the high priest who is becoming the new high priest from among his sons will offer it. As commanded forever, all of it shall be burned to Yahweh.

²³Every grain offering of the priest will be completely burned up. It must not be eaten.”

²⁴Yahweh spoke to Moses again, saying,

²⁵“Speak to Aaron and to his sons, saying, 'This is the law of the sin offering: The sin offering must be killed at the place where the burnt offering is killed before Yahweh. It is most holy.
