²⁵ and whoever carries their carcasses must wash his clothes and shall be unclean until the evening. ²⁶ You shall consider every animal to be unclean that has undivided hoofs and does not chew its cud. Whoever touches them shall be unclean. ²⁷ Every animal that walks upon all fours and walks upon its paws will be unclean to you. Whoever touches their carcasses shall be considered to be unclean until the evening.
