“Awake, O sword, against My Shepherd, Against the Man who is My Companion,” Says the LORD of hosts. “Strike the Shepherd, And the sheep will be scattered; Then I will turn My hand against the little ones.  Zechariah 13:7

As you walk through the book of Zechariah, you realize the prophet is pointing you to Jesus Christ, the fulfilment of the Messianic prophecies. Just as Jesus was the fulfilment of Zechariah’s prophecy in the Triumphant Entry riding on a donkey in Jerusalem on Palm Sunday (Zechariah 9:9) 

Here we see another fulfillment of prophecy by Jesus, as Christ predicts his disciples will abandon him when they take him away to be beaten and crucified as The Lamb of God (Isaiah 53) When you understand who Jesus Christ is, then the Old Testament scriptures and shadows make perfect sense. Without Christ, what sense would these scriptures make?

Then Jesus said to them, “This very night you will all fall away on account of Me. For it is written: ‘I will strike the Shepherd, and the sheep of the flock will be scattered.’  Matthew 26:31

Jesus clearly identifies himself as the “Good Shepherd” Jesus is The Shepherd prophesied by Zechariah here, Christ is the Good Shepherd in Psalm 23, Jesus is the Good Shepherd who lays down his life for His Sheep, Jesus is the Good Shepherd who will walk with us through the valley of death

I am the good shepherd. The good shepherd lays down His life for the sheep.  John 10:11

And it shall come to pass in all the land,” Says the LORD, “That two-thirds in it shall be cut off and die, But one-third shall be left in it:  I will bring the one-third through the fire, Will refine them as silver is refined, And test them as gold is tested. They will call on My name, And I will answer them. I will say, ‘This is My people’; And each one will say, ‘The LORD is my God.’ ”  Zechariah 13:8-9

So what about Israel? The prophet Zechariah states “in all the land” meaning Israel. And as predicted the majority “two-thirds” will reject Christ and be cut off. However “one-third” the remnant of God will be saved. They will call upon the name of Jesus and will be saved (Romans 10:13) 

As the Apostle Paul prophesied under the inspiration of the Holy Spirit, as the prophet Elijah fortold , God will always have a remnant chosen by grace. There will be a remnant of Israel that will be saved in the end, this is written and prophesied by the Word of God

In the same way, at the present time there is a remnant chosen by grace.  Romans 11:5
