Leviticus 6:3-13

3 Or hath found that which was lost, and lieth concerning it, and sweareth falsely; in any of all these that a man doeth, sinning therein:
4 Then it shall be, because he hath sinned, and is guilty, that he shall restore that which he took by force, or the thing which he obtained by deceit, or that which was delivered him to keep, or the lost thing which he found,
5 Or all that about which he hath sworn falsely; he shall even restore it in the principal, and shall add to it the fifth part more, [and] give it to him to whom it appertaineth, in the day of his trespass-offering.
6 And he shall bring his trespass-offering to the LORD, a ram without blemish out of the flock, with thy estimation, for a trespass-offering, to the priest:
7 And the priest shall make an atonement for him before the LORD: and it shall be forgiven him for any thing of all that he hath done in trespassing therein.
8 And the LORD spoke to Moses, saying,
9 Command Aaron and his sons, saying, This [is] the law of the burnt-offering: It [is] the burnt-offering, because of the burning upon the altar all night until the morning, and the fire of the altar shall be burning in it.
10 And the priest shall put on his linen garment, and his linen breeches shall he put upon his flesh, and take up the ashes which the fire hath consumed with the burnt-offering on the altar, and he shall put them beside the altar.
11 And he shall put off his garments, and put on other garments, and carry forth the ashes without the camp to a clean place.
12 And the fire upon the altar shall be burning on it; it shall not be extinguished: and the priest shall burn wood on it every morning, and lay the burnt-offering in order upon it; and he shall burn on it the fat of the peace-offerings.
13 The fire shall ever be burning upon the altar; it shall never go out.
