The laws established for the Paschal lamb, which prefigured Him and prophetically portrayed Him, must fully be applied to the sacred Lamb.
This is precisely what John indicates in verse 36. The Apostle Paul also indicates it when he says: “Christ our Pascha has been sacrificed for us” (1 Cor 5:7).
The other saying, cited by John in verse 37, is found in the Prophet Zechariah (12:10).
With great prophetic clarity, moved by the Spirit of God, he said: “Upon the house of David and upon the inhabitants of Jerusalem I will pour out the spirit of grace and compunction.
And they shall look upon Him whom they pierced, and they shall mourn for Him as one mourns for an only-begotten son.
They shall grieve as one grieves for a firstborn,” and so forth (Zech 12:10). “In that day a fountain shall be opened for the house of David and the inhabitants of Jerusalem, for washing away sin and uncleanness” (Zech 13:1).
Above, we saw the prophecy about the Lord’s sufferings depicted in Psalm 21. In the same psalm, verse 28 indicates that all the ends of the earth will remember and turn to the Lord.
All the families of the nations will worship before Him.
Therefore here too lies the answer to the question: to whom precisely does Zechariah’s saying refer, “They shall look upon Him whom they pierced”?
The Jews who handed the Lord over looked upon Him. The soldiers who crucified Him looked upon Him. The centurion guarding Him looked upon Him.
The pious men and women who reverently buried Him also looked upon Him.
In other words, representatives both of the Jews and of the Gentiles looked upon Him.
Or better, in their persons the whole world of human beings looked, and will look, upon the Pierced One.
By faith it received, and will receive, healing from the wounds of sin, according to the word and comparison of the Lord Himself.
“As Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up.
That whoever believes in Him should not perish, but have eternal life” (Jn 3:14-15).
Thus the promises of God were fulfilled, beginning with His word about the seed of the woman who was to strike the serpent.
“From being wounded in the heel, that victorious Seed of the woman, or Head and Deliverer of believers, is not excluded,” says Metropolitan Philaret.
He says this concerning God’s curse pronounced upon the serpent as the representative of the devil, in his notes on Gen 3:15.
This serpent’s sting in the heel is the wounding of which the Prophet Isaiah speaks: “By His wound we are healed” (Isa 53:5).
From this first revelation to the Incarnation of God the Word, the coming mystery appears ever more clearly throughout the Old Testament.
It appears in types, in psalms, and in prophecies.
The connection of all these prophetic indications with the Incarnation of God the Word on earth was finally disclosed to believers by the gifts of the Holy Spirit, the Comforter.
He was sent by the Lord Jesus from the Father. See Jn 15:26; 16:7-14; 20:22; Acts 1:5; and compare the first chapter of John’s Gospel, 1-18.
The study of the Old and New Testaments together reveals the whole plan of divine wisdom saving humanity.
“The very Word of God, the unchanging Image of the Father, enters into His image which is in man (Gen 1:26).
He bears flesh for the sake of flesh, and is mingled with a rational soul for the sake of my soul, cleansing like by like,” says Gregory the Theologian.
By the human soul of God, the dominion of death was destroyed, and resurrection from Hades was proclaimed to souls.
By the body of Christ, corruption was rendered powerless, and incorruption was manifested from the tomb, says Athanasius the Great.
