And sow the fields, and plant vineyards,.... And so raise a sufficient supply of corn and wine for the support of themselves and families. In a spiritual sense the "fields" are the world, and the seed which is sown is the word; the persons that sow it are the ministers of the Gospel, which, by a divine blessing, brings forth fruit, in some thirty, some sixty, and some an hundred fold: the "vineyards" are the churches, planted by Christ and by his ministers, as his instruments; believers are the pleasant plants in them, and young converts are the tender grapes
Which may yield fruits of increase; or "fruit" and "increase"; the fields yield all sorts of grain for food, and the vineyards wine for drink. So the seed of the word being sown, and churches planted, they increase with the increase of God, and bring forth fruits of righteousness to the glory of his name.
