Leviticus 11:20 specifies winged insects that walk on all fours as an abomination, illustrating the 'abominable unclean thing' in Lev 7:21.

Leviticus 11:24-42 specifies uncleanness from touching animal carcasses — directly matching the 'unclean animal' condition here.

Leviticus 11:41 declares swarming things on the ground detestable, another instance of the 'abominable' category in Lev 7:21.

Leviticus 11:42 continues listing swarming things (belly, fours, many feet) as detestable, further defining the uncleanness in Lev 7:21.
