The Character of Jewish Feasts in Biblical Worship
The three major Jewish feasts are associated with three annual harvests; historically each involved the return of a portion of the harvest to the Lord. These offerings symbolized the reasons for the feast itself: God is the source of the fruits of the earth; God’s gifts of produce are for the sustenance and comfort of the people; and because God gives freely, the worshipers must do the same, sharing their benefits with the needy.
