Num 18:32

וְלֹֽא־תִשְׂא֤וּ עָלָיו֙ חֵ֔טְא בַּהֲרִֽימְכֶ֥ם אֶת־חֶלְבּ֖וֹ מִמֶּ֑נּוּ וְאֶת־קָדְשֵׁ֧י בְנֵי־יִשְׂרָאֵ֛ל לֹ֥א תְחַלְּל֖וּ וְלֹ֥א תָמֽוּתוּ׃ פ

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.’”
