33for the showbread, the regular grain offering, the regular burnt offering, the Sabbaths, the new moons, the appointed feasts, the holy things, and the sin offerings to make atonement for Israel, and for all the work of the house of our God.

34We, the priests, the Levites, and the people, have likewise cast lots 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.
