Ephesians 6:3

When he restated the promise connected with obeying the fifth commandment, Paul changed it. God promised obedient Jewish children who lived under the Mosaic Law long life in the Promised Land (Exodus 20:12; Deuteronomy 5:16). Since He has not promised Christians a particular piece of land, Paul stated the more general promise that lay behind the specific promise, namely, longer physical life on earth. Normally children who obey their parents end up avoiding many perils that would shorten their lives.
