A kind of large lizard, called koach from its great strength (Leviticus 11:30). Kuebel makes it "the croaking frog"; Gesenius, "the Nile lizard." The word translated "the mole," tinshemeth , is rather the chameleon, literally, "the inflating animal," as it inflates its body when excited. The koach answers well to the qecko lizard, small, clumsy, hiding by day in holes, and at night coming forth to prey upon insects. They can crawl like flies on the under side of ceilings by the laminated structure of the under surface of their toes.
