From all the clean animals, take seven and seven, the male and the female. Yet truly, from animals that are unclean, take two and two, the male and the female.
Therefore, you must also separate the clean animals from the unclean, and the clean birds from the unclean. Do not pollute your souls with cattle, or birds, or anything that moves upon the earth, and which I have shown you to be unclean.
Do not be led away by changing or strange doctrines. And it is best for the heart to be sustained by grace, not by foods. For the latter have not been as useful to those who walked by them.
