MLV(i) 18 And Jehovah has avowed you this day to be a people for his own possession, as he has promised you and that you should keep all his commandments, 19 and to make you high above all nations that he has made, in praise and in name and in honor and that you may be a holy people to Jehovah your God, as he has spoken.
