'Wood offering' in the Bible

We cast lots, the priests, the Levites, and the people, for the wood offering, to bring it into the house of our God, according to our fathers' houses, at times appointed, year by year, to burn on the altar of the LORD our God, as it is written in the law;

and for the wood offering, at times appointed, and for the first fruits. Remember me, my God, for good.
