Deuteronomy 18:15-16 recalls Israel's experience at Horeb, where the people feared hearing God's voice directly and asked for a mediator. God responded by promising to raise up a prophet like Moses through whom His word would be communicated. Moses therefore serves not only as Israel's great lawgiver but also as a pattern of the divinely appointed mediator who speaks God's words to the people.

In John 5:45-47 Jesus tells His opponents that Moses himself stands as their accuser because, if they truly believed Moses, they would believe Jesus, since Moses wrote about Him. Jesus does not identify a single verse in that statement, but Deuteronomy 18 has naturally been understood as part of the Mosaic witness to Christ. This interpretation is strengthened by Acts 3:22-23, which directly applies the promised Prophet to Jesus. The fulfillment therefore rests upon the New Testament's broader claim that the writings of Moses ultimately point beyond Moses to Christ.
