Jeremiah 27:11
But the nations that bring their neck under the yoke of the king of Babylon, and serve him, those will I let remain still in their own land, saith the LORD; and they shall till it, and dwell therein. But the nations that bring their neck under the yoke of the king of Babylon, and serve him, those will I let remain still in their own land, saith the LORD; and they shall till it, and dwell therein.
The nations that would bring their neck under the yoke of the king of Babylon and serve him would be allowed by God to remain still in their own land, to till it and to dwell therein. Submission to that rule meant continuing to farm and live at home instead of being destroyed or permanently removed. For Judah this meant maintaining friendly relations with Babylon rather than resisting its rulers.
That submission was a limited, temporary period of servitude appointed by God, lasting only until He delivered them. It was the lighter and least severe punishment God could impose, sparing those who accepted it from further punishment. Refusing it and resisting the decree by war would bring harsher judgments.
The promise belongs to the prophecy that the servitude would last seventy years, after which God would deliver the captives and judge Babylon. Its setting is Jeremiah's counsel during the Babylonian captivity, and its seventy-year promise of return became clear to Daniel as he studied Jeremiah's prophecies.
