Thou shalt also be a crown of glory
Zion a crown of glory God’s hand
It is only through figurative representations that prophecy here sees what Zion will be in the future; she becomes a crown of adornment, a tiara (the head-dress of the high priest, Exodus 33:4; Zechariah 3:5; and of the King, Ezekiel 21:26) of royal dignity in the hand of Jehovah her God.
It is a leading feature in the picture that Jehovah holds the crown in His hand. Zion is not the ancient crown which the Eternal bears on His head, but she is the crown which He holds in His hand, because in Zion He is recognized by all creation; the whole history of redemption is the history of Jehovah’s taking the kingdom and bringing it to perfection, in other words, the history of the working out of this crown. (F. Delitzsch, D. D.)
