Deuteronomy 16:13-15

LITV(i) 13 You shall keep the Feast of Tabernacles seven days after you have gathered in from your threshingfloor, and from your winepress. 14 And you shall rejoice in your feast, you and your son, and your daughter, and your male slave, and your slave-girl, and the Levite, and the alien, and the fatherless, and the widow that are inside your gates. 15 You shall keep a solemn feast seven days to Jehovah your God in the place which Jehovah shall choose; for Jehovah your God shall bless you in all your produce, and in every work of your hands, and you shall be altogether joyful.
