Deuteronomy 16
10 Ref You shall keep the feast of weeks to Yahweh your God with a tribute of a freewill-offering of your hand, which you shall give, according as Yahweh your God blesses you:
11 Ref and you shall rejoice before Yahweh your God, you, and your son, and your daughter, and your man-servant, and your maid-servant, and the Levite who is within your gates, and the foreigner, and the fatherless, and the widow, who are in the midst of you, in the place which Yahweh your God shall choose, to cause his name to dwell there.
