Deuteronomy 29:25 Meaning and Commentary

Deuteronomy 29:25

Then men shall say
The answer that will be returned to the above questions will be this

because they have forsaken the covenant of the Lord God of their
fathers:
breakers of covenants with men are always reckoned among the worst of men, see ( Romans 1:31 ) ; and especially breakers of covenant with God, and with such a God as the God of Israel was, so good, so kind, and gracious; and of such a covenant he made with them, in which so many good things were promised unto them, on condition of their obedience; as the continuance in, such a land they dwelt in, with an abundance of privileges, civil and religious: and this covenant God of theirs was the God of their fathers also; and it was always reckoned an heinous sin among the Heathens to forsake the gods of their ancestors; see ( Jeremiah 2:11 ) ;

which he made with them when he brought them out of the land of Egypt;
which is another aggravation of their breach of the covenant the Lord made with them; it being made with them by that God, and at that time, when he in so wonderful a manner, with such mighty power, and a outstretched arm, and in great kindness and tenderness to them, brought then, out of hard bondage and most wretched slavery in Egypt.

24 Indeed, all nations will ask: Why did the LORD do this to this land? What led to this terrible display of anger?

25 They will deduce: It was because those people abandoned the covenant of the LORD, their ancestors' God, which he made with them when he brought them out of Egypt.

26 They followed other gods, serving them and worshipping them—other gods that they hadn't experienced before and that the Lord hadn't designated for them.

27 Then the LORD's anger burned against that land, and he brought against it every curse written in this scroll.
