Jeremiah 51:50

Ye that have escaped the sword, go away, stand not still,.... The Jews, who had escaped the sword of the Chaldeans when Jerusalem was taken, and were carried captive into Babylon, where they had remained to this time; and had also escaped the sword of the Medes and Persians, when Babylon was taken; these are bid to go away from Babylon, and go into their land, and not stay in Babylon, or linger there, as Lot in Sodom; or stop on the road, but make the best of their way to the land of Judea:

remember the Lord afar off; the worship of the Lord, as the Targum interprets it; the worship of the Lord in the sanctuary at Jerusalem, from which they were afar off at Babylon; and had been a long time, even seventy years, deprived of it, as Kimchi explains it:

and let Jerusalem come into your mind; that once famous city, the metropolis of the nation, that now lay in ruins; the temple that once stood in it, and the service of God there; that upon the remembrance of, and calling these to mind, they might be quickened and stirred up to hasten thither, and rebuild the city and temple, and restore the worship of God. It is not easy to say whose words these are, whether the words of the prophet, or of the Lord by him; or of the inhabitants of the heavens and earth, whose song may be here continued, and in it thus address the Jews.
