Deuteronomy 30:18 Meaning and Commentary

Deuteronomy 30:18

I denounce unto, you this day that ye shall surely perish,
&c.] By one judgment or another; this he most solemnly averred, and it might be depended upon that it would certainly be their case; see ( Deuteronomy 4:26 ) ;

[and that] ye shall not prolong [your] days upon the land, whither
thou passest over Jordan to go to possess it;
but be cut short by death, of one kind or another, by sword, or famine, or pestilence, or be carried into captivity; one or other of which were frequently their case.

Deuteronomy 30:18 In-Context

16 in that I am commanding thee to-day to love Jehovah thy God, to walk in His ways, and to keep His commands, and His statutes, and His judgments; and thou hast lived and multiplied, and Jehovah thy God hath blessed thee in the land whither thou art going in to possess it.
17 `And if thy heart doth turn, and thou dost not hearken, and hast been driven away, and hast bowed thyself to other gods, and served them,
18 I have declared to you this day, that ye do certainly perish, ye do not prolong days on the ground which thou art passing over the Jordan to go in thither to possess it.
19 `I have caused to testify against you to-day the heavens and the earth; life and death I have set before thee, the blessing and the reviling; and thou hast fixed on life, so that thou dost live, thou and thy seed,
20 to love Jehovah thy God, to hearken to His voice, and to cleave to Him (for He [is] thy life, and the length of thy days), to dwell on the ground which Jehovah hath sworn to thy fathers, to Abraham, to Isaac, and to Jacob, to give to them.'
