The book of Zechariah gives us a glimpse of who Jesus is in the Old Testament (O.T).
Zechariah means “Yahweh Remembers” i.e., God remembers his covenant (He will be their God and they will be His people). There are many instances in this book that has a direct reference to the Savior and Messiah (the anointed/chosen One), Jesus Christ.
Zechariah 6:12-13 talks about the coronation of Joshua (a variant of Yeshua a.k.a. Jesus) as priest who will rebuild the temple, bear the glory and shall sit and rule upon his throne as King. In Hebrews 8:1 we see Jesus Christ, THE High Priest who sits at the right hand of the Majesty in the heavens, who reigns.
Zechariah 9:9 talks about a King riding on a donkey. In Luke 19 we see Jesus riding on a donkey as He enters into Jerusalem.
Zechariah 9:10 talks about a King riding on a horse. In Revelation 19, we read about Jesus who will come riding on a white horse.
Zechariah 11:12 states that the price for the staff of the shepherd (LORD), called Beauty, that the people will agree to pay would be thirty (30) pieces of silver. In Matthew 26:15, we read that Judas covenanted to betray Jesus, the Beautiful staff of God (the Good Shepherd), for thirty (30) pieces of silver.
Zechariah 12:10 states that they shall look upon me whom they have pierced, …. In John 18:34-37, we see that Jesus was pierced on the Cross.
In Zechariah, Jesus is the High Priest and riding King. He rode once on a donkey, He will ride as King on the horse. Jesus is the Beauty of the LORD, the Staff of the Good Shepherd. He was priced and pierced for us, because Yahweh remembered his covenant with man, to be their God so that they could be His people.
