And all of the prohibited actions which are said as negative commandments on their own are not combined, like fat and blood, left-overs and abominations, but if it mentions several prohibitions and it repeats them and includes all of them with one warning – they may be combined together. As when it repeats and includes unclean types when it is written טמאים הם לכם (Of their flesh you shall not eat, and their carcasses you shall not touch; they are unclean to you)³⁹⁴, this is to teach that they may be combined together.

*Leviticus 11:8 says,*מבשרם לא תאכלו ובנבלתם לא תגעו טמאים הם לכם (Of their flesh you shall not eat, and their carcasses you shall not touch; they are unclean to you) after prohibiting the eating of several unclean animals individually. According to Rule 170, Leviticus 11:8 teaches that unforbidden quantities of different unclean animals may form forbidden quantities when combined with each other³⁹⁵.
