Charles Ellicott Commentary Deuteronomy 30:5

"and Jehovah thy God will bring thee into the land which thy fathers possessed, and thou shalt possess it; and he will do thee good, and multiply thee above thy fathers." — Deuteronomy 30:5 (ASV)

Into the land which your fathers possessed. —It is very difficult to interpret these words of any land except Palestine. Compare Jeremiah 29:13-14, for their fulfilment in the first restoration, from Babylon.
