“‘Every winged swarming thing that walks on all fours ¹  is detestable to you.

But any other winged swarming thing that has four legs is detestable to you.

or a man who touches a swarming thing by which he becomes unclean, ¹  or touches a person ²  by which he becomes unclean, whatever that person’s impurity ³  –

Or when there is ¹  a person who touches anything ceremonially ²  unclean, whether the carcass of an unclean wild animal, or the carcass of an unclean domesticated animal, or the carcass of an unclean creeping thing, even if he did not realize it, ³  but he himself has become unclean and is guilty; ⁴ 

But any creatures that do not have both fins and scales, whether in the seas or in the streams, from all the swarming things of the water and from all the living creatures that are in the water, are detestable to you.

However, this you may eat from all the winged swarming things that walk on all fours, which have jointed legs ¹  to hop with on the land.
