Deuteronomy 10:12-16

“Now, Israel, what does the LORD your God require from you, but to fear the LORD your God, to walk in all His ways and love Him, and to serve the LORD your God with all your heart and with all your soul, and to keep the LORD’S commandments and His statutes which I am commanding you today for your good? Behold, to the LORD your God belong heaven and the highest heavens, the earth and all that is in it. Yet on your fathers did the LORD set His affection to love them, and He chose their descendants after them, even you above all peoples, as it is this day. So circumcise your heart, and stiffen your neck no longer.
