Deuteronomy 6:10 Meaning and Commentary

Deuteronomy 6:10

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.

Deuteronomy 6:10 In-Context

8 And thou shalt fasten them for a sign upon thy hand, and it shall be immoveable before thine eyes.
9 And ye shall write them on the lintels of your houses and of your gates.
10 And it shall come to pass when the Lord thy God shall have brought thee into the land which he sware to thy fathers, to Abraam, and to Isaac, and to Jacob, to give thee great and beautiful cities which thou didst not build,
11 houses full of all good things which thou didst not fill, wells dug in the rock which thou didst not dig, vineyards and oliveyards which thou didst not plant, then having eaten and been filled,
12 beware lest thou forget the Lord thy God that brought thee forth out of the land of Egypt, out of the house of bondage.
