Deuteronomy 11:16-17

WEB(i) 16 Be careful, lest your heart be deceived, and you turn away to serve other gods and worship them; 17 and Yahweh’s anger be kindled against you, and he shut up the sky so that there is no rain, and the land doesn’t yield its fruit; and you perish quickly from off the good land which Yahweh gives you.
