Leviticus 6:13-16

¹³fire is continually burning on the altar, it is not quenched.

¹⁴'And this is a law of the present: sons of Aaron have brought it near before Jehovah unto the front of the altar,

¹⁵and one hath lifted up of it with his hand from the flour of the present, and from its oil, and all the frankincense which is on the present, and hath made perfume on the altar, sweet fragrance — its memorial to Jehovah.

¹⁶'And the remnant of it do Aaron and his sons eat; with unleavened things it is eaten, in the holy place, in the court of the tent of meeting they do eat it.
