Deuteronomy 11:16-17
Exhortation to Instruction and Obedience
11:16 Make sure you do not turn away to serve and worship other gods!
11:17 Then the anger of the Lord will erupt against you and he will close up the sky so that it does not rain. The land will not yield its produce, and you will soon be removed from the good land that the Lord is about to give you.
