Deuteronomy 6:10-15

10When the LORD your God brings you into the land he swore to your fathers, to Abraham, Isaac and Jacob, to give you—a land with large, flourishing cities you did not build, 11houses filled with all kinds of good things you did not provide, wells you did not dig, and vineyards and olive groves you did not plant—then when you eat and are satisfied,

12be careful that you do not forget the LORD, who brought you out of Egypt, out of the land of slavery. 13Fear the LORD your God, serve him only and take your oaths in his name. 14Do not follow other gods, the gods of the peoples around you; 15for the LORD your God, who is among you, is a jealous God and his anger will burn against you, and he will destroy you from the face of the land.
