This is closely related to the preceding psalm, and may be taken in a literal or spiritual sense. Labour in both spheres will be productive. A God-fearing man will know blessings, both in his home and in the house of God. Likewise, the Lord Jesus Christ, as Son over His house, shall see of His works and travail of soul. His bride, the church, will be as a fruitful vine. His vast progeny will sit at His table, and be fat and flourishing.

1 Blessed is each one that fears the Lord,
