Leviticus 1:8

Fire. Essentially as symbol of God's holiness. As such it expresses God in three ways:

(1) In judgment upon that which His holiness utterly condemns (e.g.) Genesis 19:24; Mark 9:43-48; Revelation 20:15.

(2) in the manifestation of Himself, and of that which He approves Exodus 3:2; 1 Peter 1:7; Exodus 13:21

and (3) in purification (e.g) 1 Corinthians 3:12-14; Malachi 3:2; Malachi 3:3. So, in Leviticus, the fire which only manifests the sweet savour of the burnt-, meal-, and peace- offerings, wholly consumes the sin-offering.

fat That which burns most quickly -- devotedness, zeal.
