'Trespass offering' in the Bible

And he shall consecrate to the LORD the days of his separation, and shall bring a lamb of the first year for a trespass-offering: but the days that were before shall be lost, because his separation was defiled.

This shall be thine of the most holy things reserved from the fire: every oblation of theirs, every meat-offering of theirs, and every sin-offering of theirs, and every trespass-offering of theirs, which they shall render to me, shall be most holy for thee and for thy sons.
