In the city - In all civil employments. In the field - in all agricultural pursuits.

Blessed [shalt] thou [be] in the (c) city, and blessed [shalt] thou [be] in the field.
(c) You will live richly.

Blessed shalt thou 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 shalt thou 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.

In the city, and in the field - Whether they were husbandmen or tradesmen, whether in the town or country, they should be preserved from the dangers of both, and have the comforts of both. How constantly must we depend upon God, both for the continuance and comfort of life! We need him at every turn: we cannot be safe, if he withdraw his protection, nor easy, if he suspends his savour: but if he bless us, go where we will, 'tis well with us.
