Or HaChaim on Deuteronomy 30:3/אור החיים על דברים ל׳:ג׳

1 ושב ה׳ אלוקיך את שבותך, "and the Lord your G'd will will bring back your captives, etc." This is a reference to some of the sanctity which the Israelites had lost to their captors, i.e. Satan, as a result of their sins. The word ושב refers to the bodily return of the Jews from exile, whereas the words ושב השם refer to the invisible part of the exile of the people, i.e. parts of their holy souls.
