Q 133 What is the reason annexed to the fifth commandment, the more to enforce it?

A. The reason annexed to the fifth commandment, in these words, That thy days may be long upon the land which the Lord thy God giveth thee,[718] is an express promise of long life and prosperity, as far as it shall serve for God’s glory and their own good, to all such as keep this commandment.[719]

Ephesians 6:2-3. Honour thy father and mother; which is the first commandment with promise; That it may be well with thee, and thou mayest live long on the earth.
