So that the generation to come of your children that shall rise up after you,.... Not the next generation, but in future times, in ages to come, at a great distance, even after the destruction of Judea by the Romans; to which Deuteronomy 29:23 seems to refer:

and the stranger that shall come from a far land; on trade and business, or for the sake of travelling, his road either lying through it, or his curiosity leading him to see it:

shall say, when they see the plagues of the land; cities and towns in ruins, fields lie uncultivated, and the whole land depopulated, and all become a barren wilderness, which was once a fruitful country, a land flowing with milk and honey:

and the sicknesses which the Lord hath laid upon it; upon the inhabitants of it, as the pestilence and other diseases, which shall have swept the land of them; see Deuteronomy 28:22. This case supposes a general departure from the worship of God to the service of idols; otherwise single individuals are punished in their own persons, as in the Deuteronomy 29:21.

How thoroughly Moses was filled with the thought, that not only individuals, but whole families, and in fact the greater portion of the nation, would fall into idolatry, is evident from the further expansion of the threat which follows, and in which he foresees in the Spirit, and foretells, the extermination of whole families, and the devastation of the land by distant nations; as in Leviticus 26:31-32. Future generations of Israel, and the stranger from a distant land, when they saw the strokes of the Lord which burst upon the land, and the utter desolation of the land, would ask whence this devastation, and receive the reply, The Lord had smitten the land thus in His anger, because its inhabitants (the Israelites) had forsaken His covenant. With regard to the construction, observe that ואמר, in Deuteronomy 29:22, is resumed in ואמרוּ, in Deuteronomy 29:24, the subject of Deuteronomy 29:22 being expanded into the general notion, "all nations" (Deuteronomy 29:24). With וראוּ, in Deuteronomy 29:22, a parenthetical clause is inserted, giving the reason for the main thought, in the form of a circumstantial clause; and to this there is attached, by a loose apposition in Deuteronomy 29:23, a still further picture of the divine strokes according to their effect upon the land. The nouns in Deuteronomy 29:23, "brimstone and salt burning," are in apposition to the strokes (plagues), and so far depend upon "they see." The description is borrowed from the character of the Dead Sea and its vicinity, to which there is an express allusion in the words, "like the overthrow of Sodom," etc., i.e., of the towns of the vale of Siddim (see at Genesis 14:2), which resembled paradise, the garden of Jehovah, before their destruction (vid., Genesis 13:10 and Genesis 19:24.).

So that the {l} generation to come of your children that shall rise up after you, and the stranger that shall come from a far land, shall say, when they see the plagues of that land, and the sicknesses which the LORD hath laid upon it;

(l) God's plagues on those who rebel against him will be so strong, that all ages will be astonished.

which...: Heb. wherewith the LORD hath made it sick

29:22-28 Idolatry would be the ruin of their nation. It is no new thing for God to bring desolating judgments on a people near to him in profession. He never does this without good reason. It concerns us to seek for the reason, that we may give glory to God, and take warning to ourselves. Thus the law of Moses leaves sinners under the curse, and rooted out of the Lord's land; but the grace of Christ toward penitent, believing sinners, plants them again in their land; and they shall no more be pulled up, being kept by the power of God.
