The sin offering and the guilt offering were compulsory sacrifices.

The sins requiring a guilt offering were more serious. These were to cover personal guilt due to unfaithfulness, deception or robbery, indicating a measure of willfulness. Three things were required of a thief: an animal sacrifice, restoration of the thing stolen and, in certain cases, a fine of 20 percent. The regulations governing these sacrifices reveal Jehovah God’s fine sense of justice. One’s position, one’s means and the degree of one’s guilt were all given consideration. (Lev. 5:1–6:7; 7:1-7) In connection with such sacrifices, the Israelites were twice reminded not to eat the blood.​—Lev. 3:17; 7:26, 27.
