For three years, the disciples could not understand a thing of what Jesus spoke. How much could Jesus teach and how much could they have learned within a short walk on the track?<quoted text>
Your argument is meaningless, since in Acts 2 and 13 the Christian community saw that it referred to Jesus and His resurrection. How did they come to know this? On the road to Emmaus Jesus opened the Scriptures to His disciples and explained how they refer to Him from the beginning.
In Acts 2, Peter lies boldly by saying, "32 God has raised this Jesus to life, and we are all witnesses of it."
He and other disciples were not witnesses to the alleged resurrection.
And here I am opening your mind on the broadband, to show the deliberately twisted and distorted translations in the OT.
