Every year on Shavuot every man is to give as he is able, according to the blessing that the Creator have given you Deuteronomy 16:16-17. They were to offer "two wave loaves of two-tenths of an ephah" which were made of fine flour, baked with leaven." This offering was to be made with the First Fruits of the harvest, Leviticus 23:17. Now, with the wave offering they were to also offer seven first-year lambs without blemish, one young bullock, two rams, with other offerings that needed to be observed, Leviticus 23:17-21. When the Israelites were required to do these offerings another important part of the feast must have been kept. When they harvested the fields, they were required to leave the corners of the field untouched and not to gather from the harvest, so that they would leave it for the poor and the stranger, Leviticus 23:22.

Shavuot/Feast of Weeks
Shavuot is known as the Feast of Weeks (Deut. 16:9-10, 16) and the Feast of the Harvest (Exo.23:16) because it originally marked the end of the seven weeks of the Passover barley harvest and the beginning of the wheat harvest (Exo. 34:22). It's described in Leviticus 23:15-22 as the second of the three feasts and all males are to come before the Creator on this day (Exodus 23:14-17; Exodus 34:22-23; Deuteronomy 16:16). The Feast of the Weeks is fifty days, which is seven weeks, after the conclusion of Passover Leviticus 23:16; Deuteronomy 16:9. It is a time to REJOICE and REMEMBER that thou was a bondsman in Egypt Deuteronomy 16:11-12. Israel is commanded to do work only that pertains to preparing for the feast, but it prohibits you from doing occupational work on this feast day Leviticus 23:21.

He said, “So let no one judge you in food or in drink, or regarding the holy days or a new moon or Sabbaths, which are a shadow of things to come. Let no man cheat you of your reward (Colossians 2:16-17)
