Matthew Poole and continuators on Jeremiah 30:3

3 For lo, the dayes come, saith the LORD, that I will bring again the captivity of my people Israel and Judah , saith the LORD, and I will cause them to return to the land that I gave to their fathers, and they shall possess it .

The reason why God would have the prophesie written was for a memorial of Gods Truth in his promises. Israel never returned as to the body of the people, but those of the ten Tribes which were Gods People did return; we read Luk. 2.36. of one Anna who was of the Tribe of Asher, and many more doubtless did return according to the Promises, chap. 3.12.14. & 23.6. & 31.1.6. Ezek. 37.21, 22.

It is uncertain whether this promise of returning to their own land, were fulfilled in those few of the ten Tribes who joined themselves with those of Iudah after they were returned from Babylon, or remaineth yet in part to be fulfilled. The former is most probable, and that there shall be no such time when the Iews shall return again to Ierusalem, and possess their own land, for it is hard now to give an account where the posterity of the ten Tribes be, by whose retu[illegible: 2 letters], the promise should be justified. Besides that the Phrase in the beginning of this verse. For lo, the dayes come, seem to import a more speedy fulfilling of the promise, then after some thousands of years, though it is certain the Iews feed themselves with some such expectations.
