Joel 1: 4: That which the palmerworm hath left hath the locust eaten; and that which the locust hath left hath the cankerworm eaten; and that which the cankerworm hath left hath the caterpiller eaten.
The palmerworm, locust, cankerworm and caterpiller are the four growth stages of a larvae to a grown insect; these four stages represent the empires of Babylon, Persia, Greece and Rome which chewed-down the Jewish Tree.
The Jews’ Torah (the Old Testament) is written in Hebrew, and each letter of the Hebrew alphabet has a numerical value assigned to it. The sum value (gematria) of each Hebrew name in Joel 1: 4 equates to the number of years the four world empires ruled.
“Gazam” (means in Hebrew, “palmerworm”) has a gematria of 50.

B.C. 538 (Persia conquered Babylon) to B.C. 330 (Greece conquered Persia) is 208 years.
“Yelequ” (means in Hebrew, “cankerworm”) has a gematria of 140.
