Gee, you mean the truth of Jesus was hidden in the OT until Jesus came and taught the Apostles what the OT said about Him?
You mean that each and everything about Jesus wasn’t spelled out explicitly in the OT, but had to be implicitly gleaned from the stories of the OT?
You mean that the truth was revealed to Paul after the fact?

HMMMMMMMMMMMMMM
You might think Peter and the11 knew the same thing, But that would be wrong.
"and He began to teach them that the Son of man must suffer many things, and be rejected of the elders and of the chief priests, and scribes, andbe killed, and after three days rise again. And He spake that saying openly and Peter took Him and beganto rebuke Him." (Mark8:31,32).
"For He taught His disciples, and said unto them, the Son of Man is delivered unto the hands of men, and they shall kill Him. And after that He is killed, He shall rise the third day. BUT THEY UNDERSTOOD NOT THAT SAYING and were afraid to ask." (Mark 9:31,32).
