Leviticus 22:5

בכל שרץ אשר יטמא לו [OR WHOSOEVER TOUCHETH] ANY PROLIFIC CREATURE BECAUSE OF WHICH (לו) HE MAY BE MADE UNCLEAN — This means: who touches any שרץ of the minimum size that is capable of communicating uncleanness, viz., a particle of the size of a lentil (cf. Sifra, Emor, Chapter 4 4; Chagigah 11a). או באדם OR A HUMAN BEING — a dead person (Sifra, Emor, Chapter 4 4). אשר יטמא לו BY WHOM HE MAY BE MADE UNCLEAN - i. e. by touching the minimum size of a portion of the dead person which is capable of transmitting uncleanness, and this is, a portion as large as an olive (Mishnah Oholot 2:1). לכל טמאתו WHATSOEVER UNCLEANNESS HE HATH — This is intended to include in the prohibition of eating holy things one who has touched a man or a woman who has an issue, or who has touched a נדה or a woman in childbirth (Sifra, Emor, Chapter 4 4).

אוֹ־אִישׁ֙ אֲשֶׁ֣ר יִגַּ֔ע בְּכׇל־שֶׁ֖רֶץ אֲשֶׁ֣ר יִטְמָא־ל֑וֹ א֤וֹ בְאָדָם֙ אֲשֶׁ֣ר יִטְמָא־ל֔וֹ לְכֹ֖ל טֻמְאָתֽוֹ׃

or whoever touches any creeping thing, whereby he may be made unclean, or a man of whom he may take uncleanness, whatever uncleanness he has;
