Verses 3-6:
"Any abominable thing," anything which the Lord has pronounced unclean and forbidden. These dietary restrictions were imposed by law upon Israel, and not upon other peoples. They were given for the primary purpose of teaching that Israel was to be a separate people from the other nations of the world, holy unto Jehovah. With the fulfillment of the Mosaic Law, the regulations regarding clean and unclean were lifted, as Acts 10:9-18 teaches. All creatures may be regarded as clean today, see 1 Timothy 4:4; Romans 14:14.
A secondary purpose of the dietary restrictions of the Laws was for reasons of health. For example, certain of the animals designated as unclean are potential carriers of disease. Both rabbit meat and pork may be carriers of a parasite, trichina, which causes the disease of trichinosis in humans.
Certain animals were designated as clean, thus acceptable for food. The criterion: animals with cloven hoof or cleft paws, and which chewed the cud were considered clean, see Leviticus 11:2-3. The text lists ten such animals:
(1) The ox.
(2) The sheep.
(3) The goat.
(4) The hart, ayyal, a stag or male deer, similar to the American eLu
(5) The roebuck, tsebi, a male roe deer.
(6) The fallow deer, yachmur, a smaller deer found in the forests and mountains of Europe and northern Asia.
(7) The wild goat, akko, or ibex.
(8) The pygarg, dishon, a variety of antelope.
(9) The wild ox, theo, a species of antelope.
(10) The chamois, zamer, probably the wild mountain sheep, known as the Barbary Sheep or Aoudad.
