Leviticus 1:8,9

The fat All the fat was to be separated from the flesh, and to be put together, to increase the flame, and to consume the other parts of the sacrifice more speedily. But the inwards shall he wash To signify the universal and perfect purity both of the inwards, or the heart, and of the legs, or ways, or actions, which was in Christ, and which should be in all Christians. And he washed not only the parts now mentioned, but all the rest, the trunk of the body and the shoulders. A sweet savour Not in itself, but as it represented Christ's offering up himself to God as a sweet- smelling savour.
