Deuteronomy 30:2, 8, 20

and return to the LORD your God, you and your children, and obey his voice in all that I command you today, with all your heart and with all your soul

And you shall again obey the voice of the LORD and keep all his commandments that I command you today.

loving the LORD your God, obeying his voice and holding fast to him, for he is your life and length of days, that you may dwell in the land that the LORD swore to your fathers, to Abraham, to Isaac, and to Jacob, to give them.”
