Leviticus 11:11

ושקץ יהיו AND THEY SHALL BE AN ABOMINABLE THING — This statement is here repeated to prohibit all things with which it (the שרץ) is mixed if they contain so much of the שרץ as to impart its taste to them (Sifra, Shemini, Section 3 9). מבשרם OF THEIR FLESH — One is,however, not prohibited in respect to the fins and the bones (Sifra, Shemini, Section 3 10). ואת נבלתם תשקצו BUT YE SHALL HAVE THEIR CARRION IN ABOMINATION — This serves to include in the category of abominable things יבחושין found in liquids which one has filtered. יבחושין are moucherons in O. F., (English = gnats).

and they shall be abominable to you; you shall not eat of their flesh, but their carcasses you shall abominate.

וְשֶׁ֖קֶץ יִהְי֣וּ לָכֶ֑ם מִבְּשָׂרָם֙ לֹ֣א תֹאכֵ֔לוּ וְאֶת־נִבְלָתָ֖ם תְּשַׁקֵּֽצוּ׃
