'Break My Covenant' in the Bible

And the LORD said unto Moses, Behold, you shall sleep with your fathers; and this people will rise up, and go play the harlot after the gods of the strangers of the land, where they go to be among them, and will forsake me, and break my covenant which I have made with them.

For when I shall have brought them into the land which I swore unto their fathers, that flows with milk and honey; and they shall have eaten and filled themselves, and grown fat; then will they turn unto other gods, and serve them, and provoke me, and break my covenant.
