Leviticus

LEVITICUS 4
If we sin unintentionally, we are still guilty. When we become aware of the sin we are to repent, or atone, for the sin.

LEVITICUS 6
If the sin of deception is committed, restitution must be made as well as atonement sacrifices.

The priests were required to keep the fire for burnt offerings going at all times.

A portion of the people's grain offerings are to be eaten by the priests. A priests grain offering, however, must be burnt completely. It is NOT to be eaten.

A portion of meat from fellowship offerings (breast and right thigh) were the priests' share to eat.
