Leviticus 11:23-28

²³and every teeming thing which is flying, which hath four feet — an abomination it is to you.

²⁴'And by these ye are made unclean, any one who is coming against their carcase is unclean till the evening;

²⁵and anyone who is lifting up aught of their carcase doth wash his garments, and hath been unclean till the evening: —

²⁶even every beast which is dividing the hoof, and is not cloven-footed, and the cud is not bringing up — unclean they are to you; any one who is coming against them is unclean.

²⁷'And any one going on its paws, among all the beasts which are going on four — unclean they are to you; any one who is coming against their carcase is unclean until the evening;

²⁸and he who is lifting up their carcase doth wash his garments, and hath been unclean until the evening — unclean they are to you.
