“Christ has been raised up from the dead, the firstfruits of those who have fallen asleep in death.

1 Corinthians 15:20-22.

Jesus was resurrected on Nisan 16, 33 C.E., the day of the year on which the Jews presented the firstfruits of the first grain crop before Jehovah God at the temple sanctuary in Jerusalem. By calling Jesus the firstfruits, Paul implied that there would be other individuals brought back from death.
