Deuteronomy 10:13

I stayed on the mountain, as at the first time, forty days and forty nights; and the LORD listened to me that time also. The LORD would not destroy you.

The LORD said to me, “Arise, take your journey before the people; and they shall go in and possess the land which I swore to their fathers to give to them.”

Now, Israel, what does the LORD your God require of you, but to fear the LORD your God, to walk in all his ways, to love him, and to serve the LORD your God with all your heart and with all your soul,

Behold, to the LORD your God belongs heaven, the heaven of heavens, and the earth, with all that is therein.

Only the LORD had a delight in your fathers to love them, and he chose their offspring after them, even you above all peoples, as it is today.

Circumcise therefore the foreskin of your heart, and be no more stiff-necked.
