Trespass Offering

Boyd’s Bible Dictionary:

This offering was closely allied to the sin offering, and in some cases offered with it as a distinct part of the same sacrifice
(Lev. 5:15; 14:13-3215If a soul commit a trespass, and sin through ignorance, in the holy things of the Lord; then he shall bring for his trespass unto the Lord a ram without blemish out of the flocks, with thy estimation by shekels of silver, after the shekel of the sanctuary, for a trespass offering: (Leviticus 5:15)
13And he shall slay the lamb in the place where he shall kill the sin offering and the burnt offering, in the holy place: for as the sin offering is the priest's, so is the trespass offering: it is most holy: 14And the priest shall take some of the blood of the trespass offering, and the priest shall put it upon the tip of the right ear of him that is to be cleansed, and upon the thumb of his right hand, and upon the great toe of his right foot: 15And the priest shall take some of the log of oil, and pour it into the palm of his own left hand: 16And the priest shall dip his right finger in the oil that is in his left hand, and shall sprinkle of the oil with his finger seven times before the Lord: 17And of the rest of the oil that is in his hand shall the priest put upon the tip of the right ear of him that is to be cleansed, and upon the thumb of his right hand, and upon the great toe of his right foot, upon the blood of the trespass offering: 18And the remnant of the oil that is in the priest's hand he shall pour upon the head of him that is to be cleansed: and the priest shall make an atonement for him before the Lord. 19And the priest shall offer the sin offering, and make an atonement for him that is to be cleansed from his uncleanness; and afterward he shall kill the burnt offering: 20And the priest shall offer the burnt offering and the meat offering upon the altar: and the priest shall make an atonement for him, and he shall be clean. 21And if he be poor, and cannot get so much; then he shall take one lamb for a trespass offering to be waved, to make an atonement for him, and one tenth deal of fine flour mingled with oil for a meat offering, and a log of oil; 22And two turtledoves, or two young pigeons, such as he is able to get; and the one shall be a sin offering, and the other a burnt offering. 23And he shall bring them on the eighth day for his cleansing unto the priest, unto the door of the tabernacle of the congregation, before the Lord. 24And the priest shall take the lamb of the trespass offering, and the log of oil, and the priest shall wave them for a wave offering before the Lord: 25And he shall kill the lamb of the trespass offering, and the priest shall take some of the blood of the trespass offering, and put it upon the tip of the right ear of him that is to be cleansed, and upon the thumb of his right hand, and upon the great toe of his right foot: 26And the priest shall pour of the oil into the palm of his own left hand: 27And the priest shall sprinkle with his right finger some of the oil that is in his left hand seven times before the Lord: 28And the priest shall put of the oil that is in his hand upon the tip of the right ear of him that is to be cleansed, and upon the thumb of his right hand, and upon the great toe of his right foot, upon the place of the blood of the trespass offering: 29And the rest of the oil that is in the priest's hand he shall put upon the head of him that is to be cleansed, to make an atonement for him before the Lord. 30And he shall offer the one of the turtledoves, or of the young pigeons, such as he can get; 31Even such as he is able to get, the one for a sin offering, and the other for a burnt offering, with the meat offering: and the priest shall make an atonement for him that is to be cleansed before the Lord. 32This is the law of him in whom is the plague of leprosy, whose hand is not able to get that which pertaineth to his cleansing. (Leviticus 14:13‑32)

From Manners and Customs of the Bible:

The trespass offering was offered in cases of trespass committed in holy things: dishonesty or falsehood in a trust; robbery joined with deceit; dishonesty and falsehood in reference to things found (Lev. 5:15-6:715If a soul commit a trespass, and sin through ignorance, in the holy things of the Lord; then he shall bring for his trespass unto the Lord a ram without blemish out of the flocks, with thy estimation by shekels of silver, after the shekel of the sanctuary, for a trespass offering: 16And he shall make amends for the harm that he hath done in the holy thing, and shall add the fifth part thereto, and give it unto the priest: and the priest shall make an atonement for him with the ram of the trespass offering, and it shall be forgiven him. 17And if a soul sin, and commit any of these things which are forbidden to be done by the commandments of the Lord; though he wist it not, yet is he guilty, and shall bear his iniquity. 18And he shall bring a ram without blemish out of the flock, with thy estimation, for a trespass offering, unto the priest: and the priest shall make an atonement for him concerning his ignorance wherein he erred and wist it not, and it shall be forgiven him. 19It is a trespass offering: he hath certainly trespassed against the Lord. 1And the Lord spake unto Moses, saying, 2If a soul sin, and commit a trespass against the Lord, and lie unto his neighbor in that which was delivered him to keep, or in fellowship, or in a thing taken away by violence, or hath deceived his neighbor; 3Or have found that which was lost, and lieth concerning it, and sweareth falsely; in any of all these that a man doeth, sinning therein: 4Then 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, 5Or 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. 6And 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: 7And 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. (Leviticus 5:15‑6:7)).
