Deuteronomy 16:9-12

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.
