(20) Because ye would not be obedient.--In return for your disobedience. The same word is employed in Deuteronomy 7:12. The use of the word in these two places might fairly be taken to mark off the intervening portion as a complete section of the discourse.

8:10-20 Moses directs to the duty of a prosperous condition. Let them always remember their Benefactor. In everything we must give thanks. Moses arms them against the temptations of a prosperous condition. When men possess large estates, or are engaged in profitable business, they find the temptation to pride, forgetfulness of God, and carnal-mindedness, very strong; and they are anxious and troubled about many things. In this the believing poor have the advantage; they more easily perceive their supplies coming from the Lord in answer to the prayer of faith; and, strange as it may seem, they find less difficulty in simply trusting him for daily bread. They taste a sweetness therein, which is generally unknown to the rich, while they are also freed from many of their temptations. Forget not God's former dealings with thee. Here is the great secret of Divine Providence. Infinite wisdom and goodness are the source of all the changes and trials believers experience. Israel had many bitter trials, but it was to do them good. Pride is natural to the human heart. Would one suppose that such a people, after their slavery at the brick-kilns, should need the thorns of the wilderness to humble them? But such is man! And they were proved that they might be humbled. None of us live a single week without giving proofs of our weakness, folly, and depravity. To broken-hearted souls alone the Saviour is precious indeed. Nothing can render the most suitable outward and inward trials effectual, but the power of the Spirit of God. See here how God's giving and our getting are reconciled, and apply it to spiritual wealth. All God's gifts are in pursuance of his promises. Moses repeats the warning he had often given of the fatal consequences of forsaking God. Those who follow others in sin, will follow them to destruction. If we do as sinners do, we must expect to fare as sinners fare.As the nations which the Lord destroyeth before your face, so shall ye perish,.... Be cut off by the sword, or cast out as they were, the same sins, particularly idolatry, being committed by them. This is to be understood of the seven nations of the land of Canaan, which the Lord would be gradually destroying when Israel came into the possession of their land; and they might righteously expect the same treatment, should they be guilty of the same sins:

because ye would not be obedient to the voice of the Lord your God; expressed in his law, especially in the two first precepts of it, which require the worship of one God, and forbid the worshipping of idols; or to the Word of the Lord, as the Targum of Jonathan, Christ, the essential Word, in whom the name of the Lord was, and whose voice Israel was to obey, Exodus 23:20.
