(At that time I stood between the LORD and you to declare to you the word of the LORD, because you were afraid of the fire and did not go up the mountain.) ~Moses
Moses was a prophet, and this is what a prophet does. He stands between the LORD and the people who need the LORD, and he tells the people the word of the LORD.
A prophet brings God's word to the people.
Jesus was the perfect prophet, and He was also the perfect Word of God (John 1). He brought Himself from God to us, the Word made flesh, because He was the only one who could do this job perfectly.
Jesus brought Himself to us; Jesus gave Himself for us.
