John Gill Commentary Deuteronomy 28

And it shall come to pass, if you shall listen diligently
unto the voice of the Lord your God
In his law, and by his prophets: to observe [and] to do all his commandments, which I command you this
day ;
for without observing them to do them, hearing them would be to little purpose, and they were all of them to be observed and done, the lesser and weightier matters of the law as they were commanded by Moses in the name of the Lord, and as they would be taught, explained, and enforced by the prophets: that the Lord your God will set you on high above all nations of the
earth :
as they were in the times of David and Solomon; (See Gill on Deuteronomy 26:19).

And all these blessings shall come on you and overtake you ,
&c.] The blessings mentioned after, which should come upon them from God from heaven, by the direction of his providence, and that freely and plentifully, and beyond your expectations and deserts, and continue with them:

if you shall hearken to the voice of the Lord your God ;
obedience to the law being the condition of their coming and continuance; for only temporal blessings in the land of Canaan are here intended, as follow.

Blessed [shall] you [be] in the city
Not only in the city of Jerusalem, where the temple would be built, and there be blessed with the service, worship, and ordinances of God, but in all other cities of the land; where they should dwell in title, large, and spacious houses, and their cities should be walled and fenced, and be very populous; yet should enjoy health, and have plenty of all sorts of provisions brought unto them, as well as prosper in all kinds of merchandise there, as Aben Ezra notes.

and blessed [shall] you [be] in the field ;
in the country villages, and in all rural employments, in sowing and planting, as the same writer observes; in all kinds of husbandry, in the culture of the fields for corn, and of vineyards and oliveyards; all should prosper and succeed, and bring forth fruit abundantly.

Blessed shall be the fruit of thy body Their children, of which they should have many, and these live; be healthful, thrive, and arrive to manhood, and increase and perpetuate their families. Grotius thinks this was eminently fulfilled in Mary, the mother of our Lord; see (Luke 1:42) ;

and the fruit of thy ground ; of their gardens, orchards, and fields; grass for the cattle, and the wheat, barley, vines, figs, pomegranates, olives, and dates for the use of men:

and the fruit of thy cattle ; which being distinguished from oxen and sheep in the following clause, must be understood of camels and asses, which were used for the carriage both of persons and burdens, and were very serviceable, and were a considerable part of their substance in those countries; see (Job 1:3) ;

the increase of thy kine, and the flocks of thy sheep ; of their cows and oxen, and of their sheep and goats, which were very increasing creatures, and in the increase of which much of their outward happiness lay; see (Psalms 144:13Psalms 144:14) .

Blessed [shall be] your basket Which the Targums of Jonathan and Jerusalem restrain to the basket of firstfruits, and the cake of the first of their dough; but it intends any and every vessel in which they put their provisions for present use, and that that should never be empty of them, and that they should always have a sufficiency.

and your store ; what remained, and was laid up in their barns, cellars, and storehouses, for future use, or in proper places for seed.
