Deuteronomy 30:20

to love the Lord your God, to listen to his voice, and cleave to him; for this [is] your life, and the length of your days, that you should dwell upon the land, which the Lord swore to your fathers, Abraam, and Isaac, and Jacob, to give to them.

That thou mayest love the Lord thy God, and that thou mayest obey his voice, and that thou mayest cleave unto him: for he is thy life, and the length of thy days: that thou mayest dwell in the land which the Lord sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give them.

to love Yahweh your God, to obey his voice, and to cling to him; for he is your life, and the length of your days, that you may dwell in the land which Yahweh swore to your fathers, to Abraham, to Isaac, and to Jacob, to give them.
