Deuteronomy 6:10-12

And when the Lord your God has taken you into the land which he gave his oath to your fathers, to Abraham, to Isaac, and to Jacob, that he would give you; with great and fair towns which were not of your building; And houses full of good things not stored up by you, and places for storing water which you did not make, and vine-gardens and olive-trees not of your planting; and you have taken food and are full; Then take care that you keep your hearts true to the Lord, who took you out of the land of Egypt, out of the prison-house.
