Charles Ellicott Commentary Deuteronomy 5:16

"Honor thy father and thy mother, as Jehovah thy God commanded thee; that thy days may be long, and that it may go well with thee, in the land which Jehovah thy God giveth thee." — Deuteronomy 5:16 (ASV)

That it may go well with thee ... —In this form St. Paul cites the commandment in the Epistle to the Ephesians (Deuteronomy 6:2–3). As to what may be made of this promise, see a Note on Deuteronomy 22:7, and a quotation from the Talmud on the point.
