I wish to correct myself and my earlier statements, and I do apologise for any wrong and misleading information posted here by me in previous times.
The fowls that creep, going upon all four, are the ancient winged dinosaurs, and not the chicken, as previously stated. In Hebrew, any fleshy creature with wings was regarded as a fowl, as the root word for fowl in Hebrew means a flying beast or animal.
Therefore the winged dinosaurs with four feet, which crept upon the earth at times, going upon all four, are the unclean meats.
Chicken are clean for consumption, and I take back my words concerning the heir of David erring in Yah'uh's laws. I was wrong. However, that does not make him God for me. He's still my equal and I know only of one God, the God of heaven who created heaven and earth, Yah'uh.
Concerning the flying creeping things or winged insects, a close study of them reveals that their rear pair of limbs differs in structure and shape from the other pairs of limbs. These rear legs also vary in function from one winged insect to another: like in bees, they are used to carry loads of pollen from flowers to the hive for the manufacture of honey. In locusts and crickets, they are used for leaping from the ground,while in some other winged insects, which are also flying creeping things, they have no specific function, though they differ in shape and structure from the rest of the four feet at the fore. (mosquitoes, flies, fleas, etc)
This reveals why in winged insects, flying creeping things, the front four feet are regarded separately from the rear two legs. Therefore Yah'uh's word is not wrong in any manner or form, but it is very right; only a matter of investigation and application of understanding and reasoned thought.
Peace be with you.
