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.

(Leviticus 11:19; 14:18) Many travellers have noticed the immense numbers of bats that are found in caverns in the East, and Mr. Layard said that on the occasion of a visit to a cavern these noisome beasts compelled him to retreat.
