so that as long as the heavens are above the earth, your days and those of your children may be multiplied in the land that the LORD swore to give your fathers.
This is so their days and their children's days may be multiplied in the land for as long as heaven is above the earth.
It gives the promised result of this continual remembrance.
18Fix these words of mine in your hearts and minds; tie them as reminders on your hands and bind them on your foreheads. 19Teach them to your children, speaking about them when you sit at home and when you walk along the road, when you lie down and when you get up. 20Write them on the doorposts of your houses and on your gates, 21so that as long as the heavens are above the earth, your days and those of your children may be multiplied in the land that the LORD swore to give your fathers. 22For if you carefully keep all these commandments I am giving you to follow— to love the LORD your God, to walk in all His ways, and to hold fast to Him— 23then the LORD will drive out all these nations before you, and you will dispossess nations greater and stronger than you. 24Every place where the sole of your foot treads will be yours. Your territory will extend from the wilderness to Lebanon, and from the Euphrates River to the Western Sea. 25No man will be able to stand against you; the LORD your God will put the fear and dread of you upon all the land, wherever you set foot, as He has promised you.
