Verse 1
burden
(See Scofield "Isaiah 13:1"), note 1.
Verse 8
because of him
There seems to be a reference here to the advance and return of Alexander (Zechariah 9:13) after the battle of Issus, who subdued the cities mentioned in Zechariah 9:1-6, and afterward returned to Greece without harming Jerusalem. But the greater meaning converges on the yet future last days (See Scofield "Acts 2:17") as the last clause of verse Zechariah 9:8 shows, for many oppressors have passed through Jerusalem since the days of Alexander.
Verse 9
behold, thy King
The events following this manifestation of Christ as King are recorded in the Gospels. The real faith of the multitude who cried, "Hosanna" is given in Matthew 21:11 and so little was Jesus deceived by His apparent reception as King, that He wept over Jerusalem and announced its impending destruction (fulfilled A.D. 70; Luke 19:38-44. The same multitude soon cried, "Crucify Him."
Verse 10
And I will cut off
Having introduced the King in Zechariah 9:9,; Zechariah 9:10 and the verses which follow look forward to the end-time and kingdom. Except in Zechariah 9:9, this present age is not seen in Zechariah.
