Numbers 18:32
Once you have presented the best part of it, you will not incur guilt because of it. But you must not defile the sacred offerings of the Israelites, or else you will die.’”
Berean Standard Bible
And ye shall bear no sin by reason of it, when ye have heaved from it the best of it: neither shall ye pollute the holy things of the children of Israel, lest ye die.
You shall bear no sin by reason of it, when you have heaved from it its best. You shall not profane the holy things of the children of Israel, that you not die.’”
