The parts which were washed were the stomach, and bowels, and feet, divided from the carcass at the knee-joint.
The priest shall burn - The verb here translated burn, is applied exclusively to the burning of the incense, to the lights of the tabernacle, and to the offerings on the altar. The primary meaning of its root seems to be to exhale odor. (See the margin of Leviticus 24:2; Exodus 30:8). The word for burning in a common way is quite different, and is applied to the burning of those parts of victims which were burned without the camp (Leviticus 4:12, Leviticus 4:21; Numbers 19:5, etc.). The importance of the distinction is great in its bearing on the meaning of the burnt-offering. The substance of the victim was regarded not as something to be consumed, but as an offering of a sweet-smelling savor sent up in the flame to Yahweh.
