Acts 3:24

Yea, and all the prophets from Samuel and them that followed after, as many as have spoken, they also told of these days.

Peter's words here show that all of the Old Testament writers bore witness to the coming of Christ and to qualities and events of the kingdom he would receive. Some have questioned whether Samuel spoke of Christ, but of course he did. It was he who anointed David king and delivered the prophecy of David's perpetual throne (2 Samuel 7:12-16), all of which was fulfilled in Christ. Some 333 prophecies of the Old Testament, embracing practically every aspect and feature of Christ's coming and of his life, sufferings, death, burial, resurrection, glorification, etc., and of the kingdom he received, - all are fulfilled in Jesus Christ.
