The end of the matter; all has been heard. Fear God and keep his commandments, for this is the whole duty of man. —Ecclesiastes 12:13

Fear God — Which is put here for all the inward worship of God, reverence, and love, and trust, and a devotedness of heart to serve and please him; and keep his commandments — This is properly added, as a necessary effect, and certain evidence of the true and genuine fear of God. Make conscience of practising whatever God enjoins, how costly, or troublesome, or dangerous soever it may be. —Benson Commentaries
