Deuteronomy 4:26 Meaning and Commentary

Deuteronomy 4:26

I call heaven and earth to witness against you this day
Should they be guilty of such a sin, since they were so strongly and publicly cautioned against it; and even the heaven and the earth were called upon as witnesses of the law being set before them, which so expressly forbids it, ( Deuteronomy 30:19 )

that ye shall soon utterly perish from off the land whereunto you go
over Jordan to possess it;
though they were now about to go over Jordan and inherit the land of Canaan, yet they would not enjoy it long, but be taken and carried captive out of it; as the ten tribes were by Shalmaneser king of Assyria, and the two tribes by Nebuchadnezzar king of Babylon, and both for their idolatry and other crimes.

Deuteronomy 4:26 In-Context

24 For the Lord thy God is a consuming fire, a jealous God.
25 And when thou shalt have begotten sons, and shalt have sons' sons, and ye shall have dwelt a long time on the land, and shall have transgressed, and made a graven image of any thing, and shall have done wickedly before the Lord your God to provoke him;
26 I call heaven and earth this day to witness against you, that ye shall surely perish from off the land, into which ye go across Jordan to inherit it there; ye shall not prolong your days upon it, but shall be utterly cut off.
27 And the Lord shall scatter you among all nations, and ye shall be left few in number among all the nations, among which the Lord shall bring you.
28 And ye shall there serve other gods, the works of the hands of men, wood and stones, which cannot see, nor can they hear, nor eat, nor smell.
