The apostolic letter to the Hebrews (the “Jews”) begins by saying: “At many times and in many ways, God spoke long ago to the fathers through the prophets. In these last days He has spoken to us through (the) Son … through Whom He created the universe (and Who was) the imprint of His being.” In John 14:9 and 10:30, Yeshua affirmed that He was indeed the revelation of God to mankind. In John 1:1 and 14, the Holy Spirit explained through John, “In the beginning was the Word. The Word was with God and the Word was God. … The Word became flesh and tabernacled among us.”
So it’s no challenge to understand that one method God used to explain His messages, delivered through the prophets over the ages, was by Yeshua amplifying them for us. Being God Incarnate, Yeshua could freely and fully illuminate the meaning of the words that His own Spirit had dictated to the various prophets.
That is why we sometimes find that Old Testament scriptures are explained by New Testament references, sometimes paraphrased by Yeshua or the Spirit of Yeshua though the apostles. On the other hand, sometimes the Old Testament context and usage of a passage helps us to grasp the full significance of it being cited in the New Testament. This comparison of “old” and “new” revelation has helped me greatly as I pursue a better understanding of scripture.
