Leviticus 11:29-38

‘Now these are to you the unclean among the swarming things which swarm on the earth: the mole, and the mouse, and the great lizard in its kinds, and the gecko, and the crocodile, and the lizard, and 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. Also anything on which one of them may fall when they are dead becomes unclean, including any wooden article, or clothing, or a skin, or a sack—any article of which use is made—it shall be put in the water and be unclean until evening, then it becomes clean. As for any earthenware vessel into which one of them may fall, whatever is in it becomes unclean and you shall break the vessel. Any of the food which may be eaten, on which water comes, shall become unclean, and any liquid which may be drunk in every vessel shall become unclean. Everything, moreover, on which part of their carcass may fall becomes unclean; an oven or a stove shall be smashed; they are unclean and shall continue as unclean to you. Nevertheless a spring or a cistern collecting water shall be clean, though the one who touches their carcass shall be unclean. If a part of their carcass falls on any seed for sowing which is to be sown, it is clean. Though if water is put on the seed and a part of their carcass falls on it, it is unclean to you.
