Targum Jonathan on Deuteronomy
that you may love the Lord thy God, to obey His Word, and keep close unto His fear; for the law in which you occupy yourselves will be your life in this world, and the prolongment of your days in the world that cometh; and you shall be gathered together at the end of the scattering, and dwell upon the land which the Lord sware to your fathers, to Abraham, Izhak, and Jakob, to give it unto them.
