The Lord called His people to flee from the land of the north (cf. Jeremiah 3:18; Jeremiah 16:15; Jeremiah 23:8; Jeremiah 31:8) where He had scattered them as the four winds (cf. Isaiah 43:5-6; Isaiah 49:12). Most of the Israelite exiles had gone into captivity in Assyria, and most of the Judean exiles went into captivity in Babylon. However, there were many other Israelites who had been taken or had fled to Egypt ( Jeremiah 43:7), Moab, Ammon, and Edom ( Jeremiah 40:11-12), Persia, and many other nations. These were Jews who later constituted the Diaspora, those who did not return to Palestine but remained dispersed throughout the ancient world. The Lord called these people to escape from Babylon among whose daughters they lived. This was a call for the Jews still living in Babylon to return home in Zechariah"s day and help rebuild their nation. But it is also, because of the context and lack of fulfillment, a prophetic call to those living in the end times to abandon the Babylon of their day (cf. Revelation 18:4-8). [source][source][source]
"Since Babylon in the post-exilic period epitomized all the suffering and indignity inflicted on Judah at the fall of Jerusalem and after, the name could stand for all lands of exile, and was not confined to the geographical area known as Babylon." [1][source]
