Christ is proclaimed in one way or another on almost every page of the Old Testament.
Job’s faith was in the resurrection.
Abraham’s faith was in the resurrection.
Ever since God declared the coming of the Curse Reverser
in Genesis chapter 4, souls were looking forward to the Messiah.
Amazing what they knew when they didn’t have the completed Scripture in their hands.
Isaiah 53 says it all perfectly.
IMHO it took a lot more faith to wait for Messiah’s coming, than to live in our day of looking back to Christ’s finished work.
He is prophesied, foreshadowed, and typed ... but "proclaimed" refers to actions taken after the fact.
There's a difference between a prophet and a disciple.
