Psalms 22:31

They — The seed last mentioned. Come — From Judea and Jerusalem (from whence the gospel was first to go forth) to the Gentile world, to the several parts whereof the apostles went upon this errand. His — God's righteousness: his wonderful grace and mercy unto mankind, in giving them Christ and the gospel; for righteousness is often put for mercy or kindness. Unto — Unto succeeding generations. Whereby David gives us a key to understand this psalm, and teaches us that he speaks not here of himself, but of things which were to be done in after — ages, even of the spreading of the gospel among the Gentiles, in the time of the New Testament. That he — They shall declare that this is the work of God, and not of man.
