Zechariah 13:7 commands the sword to strike God's shepherd, described as the man closely associated with Him, after which the sheep are scattered. Jesus Himself quotes this prophecy in Matthew 26:31 and Mark 14:27 and applies it to His approaching arrest and the scattering of His disciples. Thus the shepherd's violent striking and the disciples' scattering are direct New Testament fulfillments. The broader claim 'Both God and man' is illuminated by John 14:9, but doctrines such as Christ's divine-human identity or the atoning purpose of His death rest on the wider New Testament witness as well.
The explanation preserves Zechariah's original prophetic setting while distinguishing explicit New Testament quotation from broader Christian typological or theological application.
