TSK · Leviticus 11:1

Of every clean beast thou shalt take to thee by sevens, the male and his female: and of beasts that [are] not clean by two, the male and his female.

Every moving thing that liveth shall be meat for you; even as the green herb have I given you all things.

Ye shall therefore put difference between clean beasts and unclean, and between unclean fowls and clean: and ye shall not make your souls abominable by beast, or by fowl, or by any manner of living thing that creepeth on the ground, which I have separated from you as unclean.

But Peter said, Not so, Lord; for I have never eaten any thing that is common or unclean.
