Many people think the dietary laws of the Old Testament do not apply to us today. In this lecture, Walter Veith explains what was unclean then is still unclean now, and what was clean then is still clean now. Using his scientific background, Veith explores various animal categories like herbivores, omnivores, fish, birds, and insects, and offers insights into their anatomies and digestive systems. Learn what the laws in Leviticus say about which animals are unclean and why God would give us these restrictions for our own health.
