Charles Ellicott Commentary Zechariah 8:20-23

"Thus saith Jehovah of hosts: [It shall] yet [come to pass], that there shall come peoples, and the inhabitants of many cities; and the inhabitants of one [city] shall go to another, saying, Let us go speedily to entreat the favor of Jehovah, and to seek Jehovah of hosts: I will go also. Yea, many peoples and strong nations shall come to seek Jehovah of hosts in Jerusalem, and to entreat the favor of Jehovah. Thus saith Jehovah of hosts: In those days [it shall come to pass], that ten men shall take hold, out of all the languages of the nations, they shall take hold of the skirt of him that is a Jew, saying, We will go with you, for we have heard that God is with you." — Zechariah 8:20-23 (ASV)

The language of the promises contained in these verses is evidently borrowed from Micah 4:2; Isaiah 2:2–3. (Compare to Isaiah 45:14-17.) According to the figurative language of the Old Testament, the nations are represented as coming up to Jerusalem with the object, doubtless, of keeping the festivals there. (Zechariah 14:16–19.) But we must not look for a literal fulfilment of such prophecies. The one before us seems to be virtually fulfilled, in that through Jesus Christ (who was a Jew according to the flesh) the knowledge of the true God has been spread among most nations of the world. Still, in view of Romans 11, we are not without warrant in looking forward to a more glorious and perfect fulfilment of such prophecies as this in the unknown future.
