The Feast of First fruits is one of the three Jewish harvest feasts to thank and honor God for all he provided. The priests sacrificed Passover lambs on the 14th day of the month of Nisan, and the first day of Passover was the 15th. The Feast of First Fruits on the third day, the 16th of Nisan. This "third-day" Celebration was the same day that Jesus resurrected from the dead.

In 1 Corinthians 15:20, Paul refers to Jesus as the first fruits of the dead. He represents the first of the great harvest of souls that will resurrect to eternal life because of the new Covenant in His blood.
