How do we know the prophecies about Christ in Zechariah are true?

The prophecies found in Zechariah regarding the coming of Christ are substantiated through their fulfillment recorded in the New Testament. For example, Zechariah’s depiction of the future Messiah emphasizes His attributes, such as being the 'king' who is 'just' and 'meek,' riding on a colt (Zechariah 9:9), which aligns perfectly with the events surrounding the triumphal entry of Jesus into Jerusalem. Furthermore, the prophetic details about Christ’s betrayal for thirty pieces of silver (Zechariah 11:12-13) were literally fulfilled in the betrayal of Judas Iscariot. The continuity between the Old and New Testaments reinforces the divine inspiration behind these prophecies, affirming their truth.
