<P> By the time of classical antiquity, extensive regulations regarding Bikkurim were recorded in the classical rabbinical literature . According to Jewish law, the corners of fields, wild areas, left - overs after harvesting (gleanings), and unowned crops were not subjected to (and could not be used as) the tithe of First Fruits (they were intended to be left as charity for the poor, and other mendicants); plants from outside Israel were also prohibited from inclusion in the tithe, as was anything belonging to non-Jews . The rules also specify that each type of product had to be individually tithed, even if the numbers were balanced so that there was no difference in amount between this situation and using just some types of First Fruit as the tithe, and retaining others in their entirety . Fruit which was allocated to the tithe could not be swapped for fruit which wasn't, to the extent that wine couldn't be swapped for vinegar, and olive oil couldn't be replaced by olives; furthermore, fruits were not allowed to be individually divided if only part went to the tithe (small whole pomegranates had to be used rather than sections from a large pomegranate, for example). </P> <P> The separation of tithed produce from untithed produce was also subject to regulation . The individual (s) separating one from the other had to be ritually clean, and had to include the best produce in the tithe if a kohen (priest) lived nearby . During the act of separation, the produce was not permitted to be counted out to determine which fell under the tithe, nor to be weighed for that purpose, nor to be measured for the same reason, but instead the proportion that was to become the tithe had to be guessed at . In certain situations, such as when tithed produce became mixed with non-tithed produce (or there was uncertainty as to whether it had), the tithed produce had to be destroyed . Anyone who made mistakes in the separation of tithed produce, and anyone who consumed any of the tithe, was required to pay compensation as a guilt offering . </P> <P> The pilgrims that brought the Bikkurim to the Temple were obligated to recite a declaration, also known as the Avowal, set forth in Deuteronomy 26: 3 - 10 (cf . Mishnah, Bikkurim 3: 6). Native - born Israelites and proselytes would bring the Bikkurim and would say the Avowal, but women who brought the Bikkurim were not permitted to say the Avowal, since they were unable to claim inheritance in the Land bequeathed unto the tribes by their male lineage . This Avowal was incorporated into a beautiful and grand festive celebration with a procession of pilgrims marching up to Jerusalem and then the Temple with gold, silver or willow baskets to which live birds were tied . (Bikkurim 3: 3, 5 and 8). The pilgrims were led by flutists to the city of Jerusalem where they were greeted by dignitaries (Bikkurim 3: 3). The procession would then resume with the flutist in lead until the Temple Mount where the Levites would break out in song (Bikkurim 3: 4). The birds were given as sacrificial offerings and the declaration would be made before a priest while the basket was still on the pilgrim's shoulder (Bikkurim 3: 5 - 6). After the basket was presented to the priest, it was placed by the Altar and the pilgrim would bow and leave (Bikkurim 3: 6). </P> <P> Although some Christian churches do celebrate harvest time, the idea of giving the First Fruits to the church has been for the large part not actively observed in Western Christianity . In Eastern Orthodox Christianity, the' first fruits' tradition is kept during the Great Feast for the Transfiguration of Our Lord, held on August 6 / 19 . </P>
