Lévitique 11:37

זרע זרוע means seed of any kind of seed-plant. The word זרוע is a noun (not a passive participle, when it would be punctuated ‎זָרוע), like (Daniel 1:12) "and let them give us of pulse — זֵרוֹעִים". טהור הוא HE SHALL BE CLEAN — Scripture by means of this and the following verse teaches you that it does not become fitted and proper to be termed food and therefore to be receptive of uncleanness, until water comes upon it.

וְכִ֤י יִפֹּל֙ מִנִּבְלָתָ֔ם עַל־כׇּל־זֶ֥רַע זֵר֖וּעַ אֲשֶׁ֣ר יִזָּרֵ֑עַ טָה֖וֹר הֽוּא׃

And if any part of their carcass fall upon any sowing seed which is to be sown, it shall be clean.
