Deuteronomy 7

6-10. For thou art an holy people unto the Lord thy God--that is, set apart to the service of God, or chosen to execute the important purposes of His providence. Their selection to this high destiny was neither on account of their numerical amount (for, till after the death of Joseph, they were but a handful of people); nor because of their extraordinary merits (for they had often pursued a most perverse and unworthy conduct); but it was in consequence of the covenant or promise made with their pious forefathers; and the motives that led to that special act were such as tended not only to vindicate God's wisdom, but to illustrate His glory in diffusing the best and most precious blessings to all mankind.

11-26. Thou shalt therefore keep the commandments, and the statutes, and the judgments, which I command thee this day--In the covenant into which God entered with Israel, He promised to bestow upon them a variety of blessings so long as they continued obedient to Him as their heavenly King. He pledged His veracity that His infinite perfections would be exerted for this purpose, as well as for delivering them from every evil to which, as a people, they would be exposed. That people accordingly were truly happy as a nation, and found every promise which the faithful God made to them amply fulfilled, so long as they adhered to that obedience which was required of them. See a beautiful illustration of this in Psalms 144:12-15 .

15. the evil diseases of Egypt--(See Exodus 15:26 ). Besides those with which Pharaoh and his subjects were visited, Egypt has always been dreadfully scourged with diseases. The testimony of Moses is confirmed by the reports of many modern writers, who tell us that, notwithstanding its equal temperature and sereneness, that country has some indigenous maladies which are very malignant, such as ophthalmia, dysentery, smallpox, and the plague.

20. Moreover the Lord thy God will send the hornet among

22. lest the beasts of the field increase upon Ruler could have given them possession of the promised land at once. But, the unburied corpses of the enemy and the portions of the country that might have been left desolate for a while, would have drawn an influx of dangerous beasts. This evil would be prevented by a progressive conquest and by the use of ordinary means, which God would bless.
