Key Information
Background Insight: Vayiqra (Leviticus) 23:9-22; Shemoth (Exodus) 23:16 | 34:22; Devariym (Deuteronomy) 16:9-12, Yahusha (Joshua) 5:11, Ma'asiym (Acts) 2:1-11
Bikkur: Hebrew בִּכּוּר bikkûwr
During Feast of First Fruits, a person would go to the standing harvest of their field and take one sheaf and bring it to the priest. The lone sheaf was called the "sheaf of First Fruits." The priest would then take the sheaf and wave it before YHWH in the Temple at Jerusalem (Leviticus 23:9-11). No one could eat of the bread or roasted grain of the barley harvest until the "sheafs of First Fruits" had been presented to the Most High and accepted for Israel. This "First-Fruits" offering before YHWH would have included other offerings such as a burnt offering and a meal offering. It was to be presented in the Holy Temple in Jerusalem (where Yah has put His name) during the feast of Unleavened bread. According to scripture, this offering would have taken place on a Sunday, the day after the regular Sabbath which would fall during the seven day Feast of Unleavened Bread. This is also the day to begin the "Counting of the Omer"; a fifty day counting that leads to the next feast day, Shavuot. There are six things that these passages above lay down as the foundations for the Feast of First-Fruits in the Torah:
1. The Timing of the Feast – Leviticus 23:10
2. The Day of the Feast – Numbers 28:26; Leviticus 23:11:
3. The Duty of the Priest – Leviticus 23:11:
4. Three Offerings of the Feast – Leviticus 23:12-13; Numbers 28:27-30:
a. Burnt Offering
b. Meal Offering
c. Drink Offering
5. Prohibition of the Feast – Leviticus 23:14:
6. Command of the Feast – Leviticus 23:14:
