Verse 2. Honour thy father and mother. Ex 20:12. Comp. See Barnes "Mt 15:4".

Which is the first commandment with promise. With a promise annexed to it. The promise was, that their days should be long in the land which the Lord their God would give them. It is not to be supposed that the observance of the four first commandments would not be attended with a blessing, but no particular blessing is promised. It is true, indeed, that there is a general declaration annexed to the second commandment, that God would show mercy to thousands of generations of them that loved him, and that kept his commandments. But that is rather a declaration in regard to all the commands of God than a promise annexed to that specific commandment. It is an assurance that obedience to the law of God would be followed with blessings to a thousand generations, and is given in view of the first and second commandments together, because they related particularly to the honour that was due to God. But the promise in the fifth commandment is a special promise. It does not relate to obedience to God in general, but it is a particular assurance that they who honour their parents shall have a particular blessing as the result of that obedience.
