Final answer:
The Great Commission is a New Testament concept, but the Old Testament, particularly in prophetic books like Isaiah, has moments that foreshadow it, such as the vision of nations coming to the light of God.
Step-by-step explanation:
The concept of the Great Commission refers to Jesus's instruction to His disciples to spread His teachings to all the nations of the world. It is primarily a New Testament directive, particularly found in the Gospel of Matthew (28:16-20). However, the question seems to be looking for an Old Testament reference that foreshadows this idea.
While the Old Testament does not contain the Great Commission as such, it does include moments where the seeds of the Great Commission can be seen, such as in the prophetic books where the nations are envisioned to come to the light of God. Isaiah 49:6, for instance, can be seen as a precursor to the Great Commission, where it is said that the Servant of the Lord is to be "a light to the nations" so that God's salvation may reach the ends of the earth.
