Context Reading
17and lest you say in your heart, “My power and the might of my hand has gotten me this wealth.” 18But you shall remember Yahweh your God, for it is he who gives you power to get wealth, that he may establish his covenant which he swore to your fathers, as it is today. 19It shall be, if you shall forget Yahweh your God, and walk after other gods, and serve them and worship them, I testify against you today that you shall surely perish. 20As the nations that Yahweh makes to perish before you, so you shall perish, because you wouldn’t listen to Yahweh your God’s voice.
