Leviticus 11:23-25

²³Forsooth whatever thing of birds (that) hath four feet only, it shall be abominable to you; (But all other creatures with wings that hath four feet, they 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; (and whoever toucheth their dead bodies, shall be polluted, or defiled, and shall be unclean until the evening;)

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