Deuteronomy 11:13-21 New American Bible (Revised Edition) (NABRE)
13 [a]If, then, you truly listen to my commandments which I give you today, loving and serving the Lord, your God, with your whole heart and your whole being, 14 I will give the seasonal rain to your land, the early rain[b] and the late rain, that you may have your grain, wine and oil to gather in; 15 and I will bring forth grass in your fields for your animals. Thus you may eat and be satisfied. 16 But be careful lest your heart be so lured away that you serve other gods and bow down to them. 17 For then the anger of the Lord will flare up against you and he will close up the heavens, so that no rain will fall, and the soil will not yield its crops, and you will soon perish from the good land the Lord is giving you.
Need for Fidelity. 18 Therefore, take these words of mine into your heart and soul. Bind them on your arm as a sign, and let them be as a pendant on your forehead. 19 Teach them to your children, speaking of them when you are at home and when you are away, when you lie down and when you get up, 20 and write them on the doorposts of your houses and on your gates, 21 so that, as long as the heavens are above the earth, you and your children may live on in the land which the Lord swore to your ancestors he would give them.
