44 Then He said to them, “These are the words which I spoke to you while I was still with you, that all things must be fulfilled which were written in the Law of Moses and the Prophets and the Psalms concerning Me.” 45 And He opened their understanding, that they might comprehend the Scriptures. 46 Then He said to them, “Thus it is written, and thus it was necessary for the Christ to suffer and to rise from the dead the third day,” (Luke 24:44–46, NKJV)
The Old Testament prophecies concerning the Christ were fulfilled in Jesus. The Lord Himself explained those prophecies to His apostles, opening their minds (understanding) to comprehend their meaning. Here is a key to understanding the OT prophecy: The New Testament explains the OT prophecies about Christ. The Holy Spirit inspired the apostles and prophets of Jesus to tell us what the OT prophecies meant (see examples in Acts 2:25-31; 13:32-41; 2 Pet. 1:19-21). We cannot lay a pre-conceived template over the inspired Scriptures and demand they conform to what we have already decided. Such an approach twists the Scriptures and destroys souls (2 Pet. 3:16). We must come with open hearts to comprehend the Scriptures (Acts 17:11-12).
