And thou shalt swear, The LORD liveth, in truth, in judgment, and in righteousness; and the nations shall bless themselves in him, and in him shall they glory. Thou shalt swear, The Lord liveth - Thou shalt not bind thyself by any false god; thou shalt acknowledge Me as the Supreme. Bind thyself By me, and To me; and do this in truth, in judgment, and in righteousness.
The nations shall bless themselves in him - They shall be so fully convinced of the power and goodness of Jehovah in seeing the change wrought on thee, and the mercies heaped upon thee, that their usual mode of benediction shall be, May the God of Israel bless thee!
