'Swarmer' in the Bible

" 'And any swarmer that swarms on the land [is] detestable; it must not be eaten.

You must not eat anything that moves upon its belly or that walks on [all] fours, even any [with] numerous feet [belonging] to any swarmer that swarms on the land, because they [are] detestable.

You must not defile yourselves with any swarmer that swarms, and you must not make yourselves unclean by them and [so] be made unclean by them,

because I [am] Yahweh your God, and you must keep yourselves sanctified, so that you shall be holy, because I [am] holy. And you must not make yourselves unclean with any swarmer that moves along on the land,

or a man who touches any swarmer that is unclean for him or [who touches] a person who is unclean for him {due to} whatever his uncleanness,
