Deuteronomy 8:15

Ver. 15. Scorpions— The scorpion is a small insect, which has a bladder full of poison: the belly is divided into seven rings, from the last of which the tail proceeds, which tail is armed with one, and sometimes with two stings, whence it darts a dangerous poison; it fixes violently with its snout, and by its feet or claws, on such persons as it seizes, so that it cannot be plucked off without difficulty, and hence its name עקרב akrab. See Parkhurst on the word. The desarts of Arabia are full of these noxious creatures. See Scheuchzer on the place.
