Leviticus 11:23-25

²³Forsooth whatever thing of birds or insects hath four feet only, it shall be abominable to you;

²⁴and whoever toucheth their bodies dead by themselves, shall be polluted, or defouled, and shall be unclean till to eventide;

²⁵and if it is need, that he bear any dead thing of these or them, he shall wash his clothes, and he shall be unclean till to the going down of the sun.
