Albert Barnes Commentary Leviticus 11:29-30

"And these are they which are unclean unto you among the creeping things that creep upon the earth: the weasel, and the mouse, and the great lizard after its kind, and the gecko, and the land-crocodile, and the lizard, and the sand-lizard, and the chameleon." — Leviticus 11:29-30 (ASV)

The identification of "the creeping things" here named is not always certain. They are most likely those which were occasionally eaten. For "the Tortoise," read "the great lizard"; for "the ferret," "the gecko" (one of the lizard tribe); for "the chameleon," read "the frog" or the Nile lizard. The word translated as "snail" probably means another kind of lizard, and "the mole" is likely "the chameleon."
