During the Jewish feast of first fruits, the people made offerings of grain to the Lord out of gratitude that the new harvest that had begun. They also called it the feast of weeks and the feast of harvest. It was a precursor of Pentecost, which happened fifty days after Passover. Jesus (Yeshua‘) was the first to rise from death. His resurrection foretold a much greater harvest of lives from the dead in the second resurrection at His return.
