Deuteronomy 31:20

20 "I will bring them into a land that has plenty of milk and honey. I promised the land to their fathers. I took an oath when I promised it. In that land they will eat until they have had enough. They will get fat. When they do, they will turn to other gods and worship them. They will turn their backs on me. They will break my covenant.

Deuteronomy 31:20 Meaning and Commentary

Deuteronomy 31:20

For when I shall have brought them into the land which I
sware unto their fathers
To give it to them, and put them into the possession of it, even the land of Canaan, often thus described, and as it is by the following character:

that floweth with milk and honey;
aboundeth with all good things; see ( Exodus 3:8 ) ;

and they shall have eaten and filled themselves, and waxen fat;
that is, after they have for a considerable time enjoyed the good things of the land, and they abound with them, and increase in them, and have great fullness of them:

then will they turn unto other gods:
turn from the Lord who has brought them into all this plenty, from the fear, worship, and service of him, and turn to the worship of idols:

and serve them:
the works of men's hands, and at most but creatures, and not the Creator; than which nothing can be more absurd and stupid, as well as wicked and ungrateful:

and provoke me:
nothing being more provoking to the Lord than idolatry, it striking at his very nature, being, and glory:

and break my covenant;
now made with them; this being foretold by the Lord, which exactly came to pass in numerous instances, proves his precise foreknowledge of future events, even such as depend on the inclinations, dispositions, and wills of men.

Deuteronomy 31:20 In-Context

18 "I will certainly turn away from them on that day. I will do it because they did a very evil thing when they turned to other gods.
19 "I want you to write down a song for yourselves. Teach it to the people of Israel. Have them sing it. It will be my witness against them.
20 "I will bring them into a land that has plenty of milk and honey. I promised the land to their fathers. I took an oath when I promised it. In that land they will eat until they have had enough. They will get fat. When they do, they will turn to other gods and worship them. They will turn their backs on me. They will break my covenant.
21 "Many horrible troubles and hard times will come on them. Then the song I am giving you will be a witness against them. That is because the song will not be forgotten by their children and their children's children. I know what they are likely to do. I know it even before I bring them into the land I promised them with an oath."
22 So that day I wrote the song down. And I taught it to the people of Israel.
