"A psalm of David." None but Messiah, Jesus, was ever called to sit at Jehovah's right hand; and He, because He was David's Lord as well as his son, the great Melchizedek withal as even now seen by faith. But His glory as Head to the church His body is in no way here revealed. The mystery was great. But we are here clearly told what He will do, not for His friends, but against His foes. The smitten head over a great country appears to be either the king of the north, or Gog. Christ shines out from heaven to destroy Antichrist, etc. But here the rod of His might is sent out of Zion, to deal first with the king of the north; as finally with his great patron, the Lord of all the Russias, who will have made that king strong, and then falls himself for ever.
The next three psalms are plainly a trilogy in suited succession, following up that which set out the exaltation of Messiah on high and the coming day of His Power out Of Zion. The first two of the three are acrostics, but all are the praises of Jah (Hallelu-jah) for the deliverance of His people by Messiah.
