לֹ֤א תֵאָפֶה֙ חָמֵ֔ץ חֶלְקָ֛ם נָתַ֥תִּי אֹתָ֖הּ מֵאִשָּׁ֑י קֹ֤דֶשׁ קָֽדָשִׁים֙ הִ֔וא כַּחַטָּ֖את וְכָאָשָֽׁם׃
Targum Jonathan on Leviticus
Their portion of the residue of the mincha of My oblations given to them shall not be baked with leaven; it is most sacred, as the sin offering and as the trespass offering.
