Leviticus 11:23-28

²³Every creeping thing from among the birds, which has four feet, is an abomination to you.

²⁴And by these ye shall be defiled; every one that touches their carcases shall be unclean till the evening.

²⁵And every one that takes of their dead bodies shall wash his garments, and shall be unclean till the evening.

²⁶And whichever among the beasts divides the hoof and makes claws, and does not chew the cud, shall be unclean to you; every one that touches their dead bodies shall be unclean till evening.

²⁷And every one among all the wild beasts that moves upon its fore feet, which goes on all four, is unclean to you; every one that touches their dead bodies shall be unclean till evening.

²⁸And he that takes of their dead bodies shall wash his garments, and shall be unclean till evening: these are unclean to you.
