Of every flying creeping thing. — Rather, of all winged creeping things. Having laid down the general rule that those creatures which creep along upon their feet in the manner of quadrupeds, and which have also wings, must not be eaten, the Lawgiver now mentions those which form an exception.
Which have legs above their feet. — Better, which have knees above their hinder legs, that is, those which have the third or hindmost pair of legs much longer and stronger than ordinary insects. Those insects, therefore, in whose hindermost legs the second joint is much larger and stronger, whereby they are enabled to leap or raise themselves up with great force and leap a great distance upon the earth, are excepted. These are the locusts. The canonical law which obtained during the second Temple defines more minutely the characteristics of clean locusts. A clean locust we are told has (1) four front feet, (2) four wings, (3) two springing feet, and (4) the wings so long and broad that they cover the greater portion of the back body of the insect. If it possesses these four characteristics it is clean, whether it is with a tail or without it, and whether it has an oblong or round head.
