Jeremiah 51:50,51 - Joseph Benson’s Commentary on the Old and New Testaments

Ye that have escaped the sword Namely, the sword which wasted Babylon. Go away, stand not still This is spoken to the Jews, who, attending to the advice given them, Jeremiah 51:45, withdrew from Babylon in time, and so escaped the sword by which they otherwise might have fallen. And here they are advised to flee still farther and farther off; but amidst all to remember their native country, and in particular Jerusalem, and the God they had worshipped there; and to pray for the restoration of the city and temple; and that he would avenge himself of the Babylonians for laying them in ruins. We are confounded, because we have heard reproach The prophet here represents the words or thoughts of the pious exiles, when they heard the Babylonians speaking of Jehovah with contempt, and deriding them for worshipping him, who could not, they said, deliver his city and temple out of their hands, or preserve them from being destroyed. For strangers are come into the sanctuaries of the Lord's house The word sanctuaries, in the plural, is likewise used Psalms 73:17, though our English reads there, sanctuary. Probably the several courts of the temple are meant by sanctuaries.
