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 (for example) (Genesis 19:24); (Mark 9:43); (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); (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.
