Leviticus 11:27-31

Also whatever walks on its paws, among all the creatures that walk on all fours, are unclean to you; whoever touches their carcasses becomes unclean until evening,

and the one who picks up their carcasses shall wash his clothes and be unclean until evening; they are unclean to you.

‘Now these are to you the unclean among the swarming things which swarm on the earth: the mole, the mouse, and the great lizard in its kinds,

the gecko, the crocodile, the lizard, the sand reptile, and the chameleon.

These are to you the unclean among all the swarming things; whoever touches them when they are dead becomes unclean until evening.
