Ephesians 6:2

Which is the first commandment with promise;— The church of Rome would hence argue, that the second commandment, which forbids the worship of images, having a promise added to it, of God's shewing mercy to thousands in them that love him and keep his commandments, can be no longer obligatory under the gospel; since this which relates to honouring of parents, is said to be the first commandment with promise. But it is easy to discern the fallacy and weakness of this argument, as what is annexed to the second commandment apparently relates to the whole law, and is a general declaration of the mercy which God would shew to those who kept, not only that, but all his commandments; while this of which the Apostle speaks, is the first and only precept of the decalogue, which has a particular promise annexed to it peculiar to itself.
