Deuteronomy 16:12

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:

and you shall rejoice before Yahweh your God, you, and your son, and your daughter, and your male servant, and your female 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.

You shall keep the feast of tents seven days, after that you have gathered in from your threshing floor and from your winepress:

and you shall rejoice in your feast, you, and your son, and your daughter, and your male servant, and your female servant, and the Levite, and the foreigner, and the fatherless, and the widow, who are within your gates.
