Leviticus 3

Leviticus 3:1

Richard Challoner: Peace offerings: Peace, in the scripture language, signifies happiness, welfare or prosperity; in a word, all kind of blessings.– Such sacrifices, therefore, as were offered either on occasion of blessings received, or to obtain new favours, were called pacific or peace offerings. In these, some part of the victim was consumed with fire on the altar of God; other parts were eaten by the priests and by the persons for whom the sacrifice was offered.

Leviticus 3:9

Gregory the Dialogist: And by the precept of the law, the tail of the victim is commanded to be offered in sacrifice. In the tail, of course, is the end of the body; and he sacrifices well who brings the sacrifice of a good work to the end of the required action. — 40 Homilies on the Gospels (Homily 25)

Leviticus 3:17

Richard Challoner: Fat: It is meant of the fat, which by the prescription of the law was to be offered on God’s altar; not of the fat of meat, such as we commonly eat.
