바이크라 (레위기) 22:16

והשיאו אותם means, and they (the priests) would burden themselves with sin, באכלם את קדשיהם WHEN THEY (the non-priests) EAT THEIR HOLY THINGS which have been set apart for the purpose of heave-offering and have thereby become holy and forbidden to them. [Onkelos who translated באכלם את קדשיהם by “when they (the priests) eat them in their uncleanness” has translated it thus quite unnecessarily] (But cf. Rashi on Sanhedrin 90b). והשיאו אותם — This (the word אותם) is one of the three cases of את with a pronominal suffix occurring in the Torah which R. Ishmael explained as speaking of (referring to) the person himself who is the subject of the sentence (i. e. as being reflexive and not accusative pronouns). In the same sense did he explain (Numbers 4:13) “[And this is the law of the Nazarite] when the days of his Nazaritehood are fulfilled, יביא אותו [to the entrance of the appointed tent]” as meaning: he shall bring himself (i. e. present himself) to the entrance etc. Similarly he explained (Deuteronomy 34:6) “ויקבור אותו in the glen” as meaning: he (Moses) buried himself (i. e. he went into a cave and died there cf. Avot 5:9 and יד משה on Shemot Rabbah 10). Thus is it explained in the Sifrei Bamidbar 32 (on Numbers 6:3).

וְהִשִּׂ֤יאוּ אוֹתָם֙ עֲוֺ֣ן אַשְׁמָ֔ה בְּאׇכְלָ֖ם אֶת־קׇדְשֵׁיהֶ֑ם כִּ֛י אֲנִ֥י יְהֹוָ֖ה מְקַדְּשָֽׁם׃ {פ}

and so cause them to bear the iniquity of trespass, when they eat their holy things: for I the Lord do sanctify them.
