Leviticus 6:13-16

¹³(6:6) A perpetual fire shall be burning upon the altar; it shall not go out.

¹⁴(6:7) And this is the law of the meat-offering: one of the sons of Aaron shall bring it near before the Lord, in front of the altar.

¹⁵(6:8) And he shall lift up from it his handful, of the flour of the meat-offering, and of its oil, and all the frankincense which is upon the meat-offering, and he shall burn it upon the altar, for a sweet savor, as its memorial, unto the Lord.

¹⁶(6:9) And what is left thereof shall Aaron and his sons eat: unleavened shall it be eaten in a holy place; in the court of the tabernacle of the congregation shall they eat it.
