Please quote the verse where it says the messiah specifically will resurrect.
Isaiah also prophesies his resurrection—“he shall see his offspring; he shall prolong his days; the will of the LORD shall prosper in his hand” (Isa 53:10b
How can he “see” his offspring if he is executed unless he is resurrected? The verb “prolong” (אָרֵך) is sometimes used to refer to an everlasting (resurrected) afterlife (Ps 23:6; 91:16), and portrays the Servant’s resurrection here.
There are also a lot of figures of the resurrection in the old testament accounts.
For example:Jonah’s journey in the belly of the fish for three days and three nights has major theological significance. Jonah’s experience in the fish parallels David’s prophecy of the Messiah in his grave (Jon 2:5 cf. Ps 16:10)
Hos 6:1-2 explicitly states, “. . . for he has torn us, that he may heal us; he has struck us down, and he will bind us up. After two days he will revive us; on the third day he will raise us up, that we may live before him.”
Too much to be coincidence.
That's just a few of them.
