“and have gathered them to their own land.” There are many verses that prophesy Israel’s return to the land of Israel, the Promised Land. Although Israel did return from Babylon, this prophecy will not be fully fulfilled until in the Millennial Kingdom, as is clear from the context. [For more information on Israel’s return to the Promised Land, see commentary on Jeremiah 32:37].

“leave none of them there.” When God gathers Israel from the nations, He will leave no one behind.
