Let the field be joyful, and all that is therein,.... Not the field of the world, but of the church, separated from others by distinguishing grace; the peculiar property of Christ, cultivated and manured by his Spirit and grace, and abounding with the fruits and flowers thereof; of a wilderness becoming a fruitful field, and for that reason should rejoice, even with joy and singing, Isa 35:1, then shall all the trees of the wood rejoice; the sons of God, so called, Sol 2:3, who, though like such, in their nature state, barren and unfruitful, yet, being ingrafted into Christ, become trees of righteousness; and so have reason to rejoice at their root in Christ, their stability by him, and fruitfulness through him: Jarchi interprets this of all the governors of the people; see Eze 17:24, all this, indeed, by a prosopopoeia, may be understood of inanimate creatures; the heavens, earth, and sea, fields, woods, and trees, rejoicing, if they could, and in their way, at such great and wonderful appearances in the Gentile world; see Isa 44:23. Aben Ezra interprets all this of the heavens giving dew, the earth its increase, and the field its fruit; all which is rejoicing.
