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