Deuteronomy 10:12-16

“And now, Israel, what does the LORD your God require from you, but to fear [and worship] the LORD your God [with awe-filled reverence and profound respect], to walk [that is, to live each and every day] in all His ways and to love Him, and to serve the LORD your God with all your heart and with all your soul [your choices, your thoughts, your whole being], and to keep the commandments of the LORD and His statutes which I am commanding you today for your good? Behold, the heavens and the highest of heavens belong to the LORD your God, the earth and all that is in it. Yet the LORD had a delight in loving your fathers and set His affection on them, and He chose their descendants after them, you above all peoples, as it is this day. So circumcise [that is, remove sin from] your heart, and be stiff-necked (stubborn, obstinate) no longer.
