Charles Ellicott Commentary Zechariah 8:7

"Thus saith Jehovah of hosts: Behold, I will save my people from the east country, and from the west country;" — Zechariah 8:7 (ASV)

From the east ... and from the west. —There were Jews in exile in the west as well as in the east (Joel 3:6); and, indeed, a very general dispersion may be almost implied from Isaiah 43:5-6.
