Jesus told the apostles to make provisions, explaining,
“For I say to you that this which is written must still be accomplished in Me: ‘And He was numbered with the transgressors.’ For the things concerning Me have an end” (Luke 22:37).
Whatever the prophets had written of the Messiah, those things had to be fulfilled in Jesus, namely, the part that He would be numbered with the transgressors, as Isaiah foretold (Isaiah 53).
Jesus explained further that those things concerning Him had an end. Nothing would be unfulfilled. Jesus is the Christ, the Son of the living God.
