I will raise up for them a Prophet like you from among their brethren, and will put My words in His mouth, and He shall speak to them all that I command Him.

As attested to by Peter at Pentecost (Acts 2:22,23) and Stephen (Acts 7:37), this Jesus was the Messiah whom the disciples proclaimed "We have found him of whom Moses in the Law and also the prophets wrote, Jesus of Nazareth, the son of Joseph." John 1:45), and who was crucified, buried but rose again, paying the price for our sins. This is the grace of God.
