Deuteronomy 16:9-17

Starting from the day you put the sickle to the ripe grain, count out seven weeks. Celebrate the Feast-of-Weeks to GOD, your God, by bringing your Freewill-Offering—give as generously as GOD, your God, has blessed you. Rejoice in the Presence of GOD, your God: you, your son, your daughter, your servant, your maid, the Levite who lives in your neighborhood, the foreigner, the orphan and widow among you; rejoice at the place GOD, your God, will set aside to be worshiped. Don’t forget that you were once a slave in Egypt. So be diligent in observing these regulations. Observe the Feast-of-Booths for seven days when you gather the harvest from your threshing-floor and your wine-vat. Rejoice at your festival: you, your son, your daughter, your servant, your maid, the Levite, the foreigner, and the orphans and widows who live in your neighborhood. Celebrate the Feast to GOD, your God, for seven days at the place GOD designates. GOD, your God, has been blessing you in your harvest and in all your work, so make a day of it—really celebrate! All your men must appear before GOD, your God, three times each year at the place he designates: at the Feast-of-Unraised-Bread (Passover), at the Feast-of-Weeks, and at the Feast-of-Booths. No one is to show up in the Presence of GOD empty-handed; each man must bring as much as he can manage, giving generously in response to the blessings of GOD, your God. * * *
