Well before Paul, Jesus revealed to His disciples--
Luk 24:25 Then he said unto them, O fools, and slow of heart to believe all that the prophets have spoken:
Luk 24:26 Ought not Christ to have suffered these things, and to enter into his glory?
Luk 24:27 And beginning at Moses and all the prophets, he expounded unto them in all the scriptures the things concerning himself.
Luk 24:44 And he said unto them, These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me.
Luk 24:45 Then opened he their understanding, that they might understand the scriptures,
Luk 24:46 And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day:
Luk 24:47 And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.
Luk 24:48 And ye are witnesses of these things.
Luk 24:49 And, behold, I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye be endued with power from on high.
