Bat

The Hebrew word (atalleph') so rendered (Lev. 11:19; Deut. 14:18) implies "flying in the dark." The bat is reckoned among the birds in the list of unclean animals. To cast idols to the "moles and to the bats" means to carry them into dark caverns or desolate places to which these animals resort (Isa. 2:20), i.e., to consign them to desolation or ruin.

עטלף, Lev. xi, 19; Deut. xiv, 18; Isaiah ii, 20; Baruch vi, 22. The Jewish legislator, having enumerated the animals legally unclean, as well beasts as birds, closes his catalogue with a creature whose equivocal properties seem to exclude it from both those classes: it is too much a bird to be properly a mouse, and too much a mouse to be properly a bird. The bat is therefore well described in Deut. xiv, 18, 19, as the passage should be read, “Moreover the _othelaph_, and _every creeping thing that flieth_, is unclean to you: they shall not be eaten.” This character is very descriptive, and places this creature at the head of a class of which he is a clear and well-known instance. It has feet or claws growing out of its pinions, and contradicts the general order of nature, by creeping with the instruments of its flight. The Hebrew name of the bat is from עטל _darkness_, and עמ _to fly_, as if it described “the flier in darkness.” So the Greeks called the creature νυκτερὶς, from νὺξ, _night_; and the Latins, _vespertilio_, from _vesper_, “evening.” It is prophesied, Isaiah ii, 20, “In that day shall they cast away their idols to the moles and to the bats;” that is, they shall carry them into the dark caverns, old ruins, or desolate places, to which they shall fly for refuge, and so shall give them up, and relinquish them to the filthy animals that frequent such places, and have taken possession of them as their proper habitation.
