Hear, O Israel: Thou art to pass over Jordan {a} this day, to go in to possess nations greater and mightier than thyself, cities great and fenced up to heaven,

(a) Meaning shortly.

Wesley's Notes

9:1 Hear, O Israel - This seems to be a new discourse, delivered at some distance of time from the former, probably on the next sabbath - day. This day - That is, shortly, within a little time, the word day being often put for time. Nations - That is, the land of those nations. Mightier than thyself - This he adds, that they might not trust to their own strength, but rely upon God's help for the destroying them, and, after the work was done, might ascribe the glory of it to God alone, and not to themselves.

Jamieson-Fausset-Brown Bible Commentary

CHAPTER 9

De 9:1-25. Moses Dissuades Them from the Opinion of Their Own Righteousness.

1. this day-means this time. The Israelites had reached the confines of the promised land, but were obliged, to their great mortification, to return. But now they certainly were to enter it. No obstacle could prevent their possession; neither the fortified defenses of the towns, nor the resistance of the gigantic inhabitants of whom they had received from the spies so formidable a description.

cities great and fenced up to heaven-Oriental cities generally cover a much greater space than those in Europe; for the houses often stand apart with gardens and fields intervening. They are almost all surrounded with walls built of burnt or sun-dried bricks, about forty feet in height. All classes in the East, but especially the nomad tribes, in their ignorance of engineering and artillery, would have abandoned in despair the idea of an assault on a walled town, which to-day would be demolished in a few hours.

Matthew Henry's Concise Commentary

9:1-6 Moses represents the strength of the enemies they were now to encounter. This was to drive them to God, and engage their hope in him. He assures them of victory, by the presence of God with them. He cautions them not to have the least thought of their own righteousness, as if that procured this favour at God's hand. In Christ we have both righteousness and strength; in Him we must glory, not in ourselves, nor in any sufficiency of our own. It is for the wickedness of these nations that God drives them out. All whom God rejects, are rejected for their own wickedness; but none whom he accepts are accepted for their own righteousness. Thus boasting is for ever done away: see Eph 2:9,11,12.
