Leviticus 1:8 - Ellicott's Commentary On The Whole Bible

Shall lay the parts. — Better, shall lay the pieces in order, as in Leviticus 1:12. The word here rendered by parts is the same which is more properly translated pieces in Leviticus 1:6. Here again the priests are not to lay the pieces upon the altar anyhow, but are to arrange them systematically. In consequence of the order expressed in this verse, the rule obtained during the second Temple that the parts of the victim should as much as possible be arranged in the same order which they occupied in the animal when alive.
