That thou mayest fear , etc. It was not mere outward observance of the Law, not the mere "doing" of what was enjoined that was required, but the doing of it heartily and sincerely in the fear of the Lord, in the fear of him who had revealed himself to them by the glorious and awful Name, Jehovah, their God (cf. Le Deuteronomy 24:11 ).
