How should we observe the Feast of Weeks / Shavu'ot / Pentecost?

Answer From The Annual Reading Schedule - Week 28 Notes For Leviticus: First of all, for any observance we must remember that Yahweh does not like iniquity or unrighteousness and assembly to be mixed together (Isaiah 1:13). What this means is that we cannot be hypocritical. We can't be pretending to follow Yahweh when it comes time for an observance, and then on all other days living wickedly without any regard for the laws of Yahweh. We can't oppress the poor, the fatherless, and the widow a day before a feast, keep the feast and rest, and then go back to oppression the day after the feast and expect that Yahweh will be pleased with us.

We need to make sure that we are not pretending and that we are looking at the way we live and our hearts to see if they are in line with Yahweh's laws. If we're just pretending on feast days and other observances and not really following Yahweh in the rest of our life, then He will not be pleased with our fake attempts to keep His Set-Apart Days. Now, to the specifics of this question:

The Feast of Weeks is mentioned in this reading from the end of Leviticus 23:16 (where it says to bring a new grain offering) until Leviticus 23:21. We can see there were two loaves of bread baked with leaven that were to be brought in Leviticus 23:17. I learned from another brother that the loaves baked with leaven were accepted even as we, although we have sinned, are made acceptable to Yahweh through the blood of Yahushua. Although we have had leaven in us, we are accepted by Yahweh.

I do not think we can literally fulfill the bringing of loaves with leaven because they were brought to the priest and waved by him as recorded in Leviticus 23:20. Since we have no physical temple with physical Sons of Aharon (Aaron) to serve, we cannot fulfill this part of the Feast of Weeks. However, if we had our own land and grew wheat, we could take some of the first fruits of the wheat harvest and give them to the poor. That could be a gesture to show Yahweh our desire to give Him the first fruits, because it is written:

Proverbs 19:17 "He who shows favor to the poor lends to Yahweh, And He repays his deed."

So, in a way, giving to the poor is like showing Yahweh you wanted to give it to Him. However, since this is a Set-Apart day I would probably not do this on the actual day of the Feast of Weeks. If I were going to give, I might give after the Feast day is over because on the Feast Day we're supposed to focus on having a Set-Apart Gathering, rejoicing, and giving thanks for the first fruits of the wheat harvest.

To prepare for this day, I would cook 2 days' worth of food 2 days prior to the Feast of Weeks. That would give you enough food for the 7th Shabbat and the Feast of Weeks so that you don't have to cook on the Feast of Weeks. The Feast of Weeks is known in Greek as Pentecost (pente – referring to the 50 day count) and in Hebrew as Shavu'ot (Shavua means Week in Hebrew and Shavu'ot is plural).

Ideal times to gather on this day for prayer and offering of praises and giving of thanks to Yahweh are the times of the morning and evening offerings at the 3rd and 9th hours of the day, and perhaps also the 6th hour of the day. At some point, probably morning, afternoon, or both if you want, you should have a Set-Apart Gathering for Reading of the Scriptures. Don't forget that a Set-Apart Gathering for Reading the Scriptures is required on this day. Also, don't forget that we're commanded to not work on this day – so it should be treated the same as a weekly Sabbath.

This is a good day to remember the Giving of the Torah on Mount Sinai in Exodus 20 as it is believed this was the day in which it was given; and the events in Acts 2 when they were gathered on this day and the Set-Apart Spirit was given also and poured out on many; and the Good News of Yahushua the Anointed was spoken and 3,000 were immersed in His name! Side Note: It is interesting that 3,000 were immersed in Acts 2 because in Exodus 32:28 about 3,000 fell.
