Matthew Poole and continuators on Jeremiah 51:50

50 Ye that have escaped the sword, go away, stand not still : remember the LORD afar off , and let Jerusalem come into your mind .

It is hard to resolve whether the Prophet here speaks to the Chaldeans or the Medes or the Iews, though most understand it of the Iews whom God would have leave Babylon as soon as they should have a liberty proclaimed.

And to remember when they came in to Iudea the great things both of Justice toward the Chaldeans, and Mercy toward them, which God had done.

And keep Ierusalem in their mind, as the place where they were to worship God according to his direction, and for which God had so wrought.
