Deuteronomy 16:9 MSG

[9] 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.
