Feast of Unleavened Bread came the day after Passover and for seven days, no leaven could be eaten or found in any of the Israelite houses [Lev. 23:6-8; I Cor. 11:23-26; 5:6-8; 2 Cor. 7:1; Gal. 5:7-9]. The leaven symbolized sin which one was to be purged from during this feast [I Cor. 5:6-8]. The first and seventh day are Sabbaths, meaning no work is to be done. In the New Testament, the Messiah laid in the tomb during this feast of the Jews. It was this Sabbath which happened to fall on a regular weekly Sabbath, that after preparing spices to anoint His body, Mary and the other women rested and waited until the next morning to go to prepare the body [Lk. 23:50-56].
Feast of First Fruits is celebrated on the 16th day of Abib (1st Hebrew month). On this day Jews were commanded to bring the first fruits of all their increase unto YHWH [Lev. 23:9-14]. In the New Testament, according to the Law, the Messiah became the “First Fruit” among many bretheren that would be resurrected or quickened to become the Sons of YHWH [I Cor. 15:23; I Thes. 4:13-18]. When Mary and the women who were with her returned to the sepulcher, instead of the body of Yahshua, [the Messiah] they found an angel who informed them that He had risen from the dead! [Lk. 24:1-8].
