10 It shall be, when Yahweh your God shall bring you into the land which he swore to your fathers, to Abraham, to Isaac, and to Jacob, to give you, great and goodly cities, which you didn't build,

And it shall be, when the Lord thy God. Since wealth and prosperity for the most part blind men's minds, so that they do not sufficiently attend to modesty and moderation, but rather grow wanton in their lusts, and intoxicate themselves with pleasures, God prescribes against this error by anticipation. For not without cause does he admonish them to beware lest they forget God, when they shall have been liberally and luxuriously treated by Him, but because he knew this to be a common vice, for abundance to beget arrogance; as afterwards he will say in his song, "Jeshurun waxed fat and kicked: thou art waxen fat, etc., then he forsook God which made him, and lightly esteemed the Rock of his salvation." (Deuteronomy 32:15.) First of all, he shews how base and unworthy would be their ingratitude, if, when loaded with so many excellent benefits by God, they should cast away the recollection of Him; for, as His goodness was inestimable, in giving them cities built by the hands of others, and in transferring to them whatever others had prepared by their great labor and industry, so would their impiety be the more detestable in neglecting Him, when He daily set Himself before them in this abundant store of blessing. Let us learn, therefore, from this passage, that we are invited by God's liberality to honor Him, and that whenever He deals kindly by us, He places His glory before our eyes; but, on the other hand, we should remember, that what ought to be as it were vehicles, to lift up our minds on high, are, by our own fault, converted into obstacles and clogs, and that therefore we ought to be the more upon our guard. At the end of verse 12, he reproves their folly by another argument, if being thus suddenly enriched, they should give way to intemperance; as if he had said, that their absurdity would be insupportable, if, when uplifted by God's bounty, they should not remember their origin; for nothing should have served more to incline them to humility than that wretched state of servitude from whence they had been rescued. Therefore he contrasts with that ample dominion to which God had exalted them, the house of bondmen," [1] in order that the recollection of their former lot may restrain all frowardness.
1 - Margin of A. V.
The Israelites were at the point of quitting a normal, life for a fixed and settled abode in the midst of other nations; they were exchanging a condition of comparative poverty for great and goodly cities, houses and vineyards. There was therefore before them a double danger;
(1) a God-forgetting worldliness, and
(2) a false tolerance of the idolatries practiced by those about to become their neighbors.
The former error Moses strives to guard against in the verses before us; the latter in Deuteronomy 7:1-11.
And it shall be, when the Lord thy God shall have brought thee into the land,.... The land of Canaan, on the borders of which they now were, and were just going into:
which he sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give thee; of his own free favour and good will, without any merit and desert of theirs, and in which would be found
great and goodly cities, which thou buildedst not; large and capacious, delightfully situated, well built, and strongly fortified, without any pains or expense of theirs; all ready for them to take possession of, and dwell in; and so should no longer reside in tents or booths, as they had for forty years past, but in spacious and noble cities.
To the positive statement of the command there is attached, in the next place, the negative side, or a warning against the danger to which prosperity and an abundance of earthly goods so certainly exposed, viz., of forgetting the Lord and His manifestations of mercy. The Israelites were all the more exposed to this danger, as their entrance into Canaan brought them into the possession of all the things conducive to well-being, in which the land abounded, without being under the necessity of procuring these things by the labour of their own hands; - into the possession, namely, of great and beautiful towns which they had not built, of houses full of all kinds of good things which they had not filled, of wells ready made which they had not dug, of vineyards and olive-plantations which they had not planted. - The nouns ערים, etc. are formally dependent upon לך לתת, and serve as a detailed description of the land into which the Lord was about to lead His people.
