1 And the LORD spake unto Moses, saying, 2 If a soul sin, and commit a trespass against the LORD, and lie unto his neighbour in that which was delivered him to keep, or in fellowship, or in a thing taken away by violence, or hath deceived his neighbour; 3 Or have 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 violently away, or the thing which he hath deceitfully gotten, 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 the fifth part more thereto, and give it unto him to whom it appertaineth, in the day of his trespass offering. 6 And he shall bring his trespass offering unto the LORD, a ram without blemish out of the flock, with thy estimation, for a trespass offering, unto 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 spake unto 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 unto 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 unto a clean place. 12 And the fire upon the altar shall be burning in it; it shall not be put out: and the priest shall burn wood on it every morning, and lay the burnt offering in order upon it; and he shall burn thereon the fat of the peace offerings. 13 The fire shall ever be burning upon the altar; it shall never go out. 14 And this is the law of the meat offering: the sons of Aaron shall offer it before the LORD, before the altar. 15 And he shall take of it his handful, of the flour of the meat offering, and of the oil thereof, and all the frankincense which is upon the meat offering, and shall burn it upon the altar for a sweet savour, even the memorial of it, unto the LORD. 16 And the remainder thereof shall Aaron and his sons eat: with unleavened bread shall it be eaten in the holy place; in the court of the tabernacle of the congregation they shall eat it. 17 It shall not be baken with leaven. I have given it unto them for their portion of my offerings made by fire; it is most holy, as is the sin offering, and as the trespass offering. 18 All the males among the children of Aaron shall eat of it. It shall be a statute for ever in your generations concerning the offerings of the LORD made by fire: every one that toucheth them shall be holy. 19 And the LORD spake unto Moses, saying, 20 This is the offering of Aaron and of his sons, which they shall offer unto the LORD in the day when he is anointed; the tenth part of an ephah of fine flour for a meat offering perpetual, half of it in the morning, and half thereof at night. 21 In a pan it shall be made with oil; and when it is baken, thou shalt bring it in: and the baken pieces of the meat offering shalt thou offer for a sweet savour unto the LORD. 22 And the priest of his sons that is anointed in his stead shall offer it: it is a statute for ever unto the LORD, it shall be wholly burnt. 23 For every meat offering for the priest shall be wholly burnt: it shall not be eaten. 24 And the LORD spake unto Moses, saying, 25 Speak unto Aaron and to his sons, saying, This is the law of the sin offering: In the place where the burnt offering is killed shall the sin offering be killed before the LORD: it is most holy. 26 The priest that offereth it for sin shall eat it: in the holy place shall it be eaten, in the court of the tabernacle of the congregation. 27 Whatsoever shall touch the flesh thereof shall be holy: and when there is sprinkled of the blood thereof upon any garment, thou shalt wash that whereon it was sprinkled in the holy place. 28 But the earthen vessel wherein it is sodden shall be broken: and if it be sodden in a brasen pot, it shall be both scoured, and rinsed in water. 29 All the males among the priests shall eat thereof: it is most holy. 30 And no sin offering, whereof any of the blood is brought into the tabernacle of the congregation to reconcile withal in the holy place, shall be eaten: it shall be burnt in the fire.
[AD 430] Augustine of Hippo on Leviticus 6:3
Shall we therefore say that when it is written that whoever finds another man’s property of any kind that has been lost, should return it to him who has lost it, doesn’t pertain to us? Do not many other like things pertain whereby people learn to live piously and uprightly? Isn’t especially the Decalogue itself, which is contained in those two tables of stone, apart from the carnal observance of the sabbath, which signifies spiritual sanctification and rest?

[AD 604] Gregory the Dialogist on Leviticus 6:5
Some people consider the commandments of the Old Testament stricter than those of the New, but they are deceived by such a shortsighted interpretation. In the former theft, not miserliness, is punished; wrongful taking of property is punished in the latter by fourfold restitution. In this place the rich man is not censured for having taken away someone else’s property but for not having sufficiently given away his own.

[AD 391] Pacian of Barcelona on Leviticus 6:9
That fire is perpetual that is never extinguished on the altar. The altar of God is our heart. Fire must always burn in it, for the flame of charity must always burn on it for God. Day by day, the priest puts wood on the fire, lest it go out. Everyone who has faith in Christ has been made a member of the high priest. The apostle Peter says to all the faithful, “You are an elect people, a royal priesthood.” The apostle John says, “You have made us a kingdom and a priesthood for our God.” The priest who feeds the fire on the altar and puts wood on it each day is each one of the faithful. To keep the flame of charity from going out in himself, he does not cease to gather both the examples of the elders and the testimonies of Holy Scripture. To call to mind the examples of the fathers or the precepts of the Lord in the practice of charity is to put fuel on the fire. Since this inner newness of ours grows old in the daily living of life, wood must be used to feed that fire. While the fire grows dim as we age, it grows bright again through the testimonies and examples of the fathers. And the command is good, to gather wood each day in the morning. This cannot be done except when the night of darkness is banished. Since morning is the first part of the day and comes when we have put off thoughts of this present life, each of the faithful should think of this task first so that the practice of charity can inflame whatever is just about to die out in him, by the efforts he can make. For that fire on the altar of God— that is, in our hearts—is soon extinguished unless it is carefully maintained by the examples of the fathers and the testimonies of the Lord.

[AD 735] Bede on Leviticus 6:9
A holocaust is burned on the altar when a good work is performed with the burning fire of charity in the heart of any elect person who is devoted to God completely (that is, with both body and soul). This is done all night until the morning when one does not cease to persevere in good works throughout all the time of his life, until one is taken from the body and merits seeing the morning of the world to come. The fire will be on the same altar, because we ought to be burning with that charity alone which the Lord gives to his church through the Holy Spirit.

[AD 735] Bede on Leviticus 6:10
The priest who offers the holocaust is the Lord who is himself accustomed to kindle in us the fire of his charity and through it to make the sacrifices of our good actions acceptable to himself. And he is clothed in linen garments when he does these things because, in order that he may excite us to works of virtue, he sets before us the examples of his own incarnation, passion and death, which can be signified by linen, as we have frequently said.

[AD 1781] Richard Challoner on Leviticus 6:13
The perpetual fire: This fire came from heaven, (infra. chap. 9. 24,) and was always kept burning on the altar, as a figure of the heavenly fire of divine love, which ought to be always burning in the heart of a Christian.
