Jamieson, Fausset and Brown on Jeremiah 23:7-8

7-8. Repeated from Jr 16:14, 15. The prophet said the same things often, in order that his sayings might make the more impression. The same promise as in Jr 23:3, 4. The wide dispersion of the Jews at the Babylonish captivity prefigures their present wider dispersion (Is 11:11; Joe 3:6). Their second deliverance is to exceed far the former one from Egypt. But the deliverance from Babylon was inferior to that from Egypt in respect to the miracles performed and the numbers delivered. The final deliverance under Messiah must, therefore, be meant, of which that from Babylon was the earnest.
