C. F. Keil and Franz Delitzsch on Deuteronomy 6:10-11

Deu 6:10-11

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.
