Scorpion in Fausset's Bible Dictionary
'akrab. Of the class Arachnida and order Pulmonaria. Common in
the Sinai wilderness, typifying Satan and his malicious agents
against the Lord's people (Deuteronomy 8:15; Ezekiel 2:6; Luke
10:19). Rolling itself together it might be mistaken for an
egg (Luke 11:12). Found in dry dark places amidst ruins, in
hot climates. Carnivorous, breathing like spiders by lung-
sacs, moving with uplifted tail.
The sting at the tail's end has at its base a gland
which discharges poison into the wound from two openings. In
Revelation 9:3; Revelation 9:10, "the scorpions of the earth"
stand in Contrast to the "locusts" from hell, not earth. The
"five months" are thought to refer to the 150 prophetical
days, i.e. years, from A.D. 612, when Mahomet opened his
mission, to 762, when the caliphate was moved to Bagdad. In 1
Kings 12:11 scorpions mean "scourges armed with iron points".
The sting of the common scorpion is not very severe, except
that of Buthus occitanus.
