Leviticus 11:13-28

‘These you shall detest among the birds; they are not to be eaten, for they are hated things: the eagle and the vulture and the buzzard, the kite, every kind of falcon, every kind of raven, the ostrich, the nighthawk, the sea gull, every species of hawk, the little owl and the cormorant and the great owl, the white owl, the pelican, the carrion vulture, the stork, all kinds of heron, the hoopoe, and the bat. ‘All winged insects that walk on all fours are detestable to you; yet of all winged insects that walk on all fours you may eat those which have legs above their feet with which to leap on the ground. Of these you may eat: the whole species of migratory locust, of bald locust, of cricket, and of grasshopper. [Matt 3:4] But all other winged insects which are four footed are detestable to you. ‘By [contact with] these you will become unclean; whoever touches their carcasses becomes unclean until the evening (dusk), and whoever picks up any of their carcasses shall wash his clothes and be unclean until the evening. Concerning all the animals which divide the hoof, but do not have a split hoof, or which do not chew the cud, they are unclean to you; whoever touches them becomes unclean. Also all animals that walk on their paws, among all kinds of animals that walk on four legs, are unclean to you; whoever touches their carcasses becomes unclean until the evening, and the one who picks up their carcasses shall wash his clothes and be unclean until the evening; they are unclean to you.
