Deuteronomy 16:13-15 King James Version (KJV)
13 Thou shalt observe the feast of tabernacles seven days, after that thou hast gathered in thy corn and thy wine:
14 And thou shalt rejoice in thy feast, thou, and thy son, and thy daughter, and thy manservant, and thy maidservant, and the Levite, the stranger, and the fatherless, and the widow, that are within thy gates.
15 Seven days shalt thou keep a solemn feast unto the Lord thy God in the place which the Lord shall choose: because the Lord thy God shall bless thee in all thine increase, and in all the works of thine hands, therefore thou shalt surely rejoice.
Deuteronomy 16:13-15 New International Version (NIV)
The Festival of Tabernacles
13 Celebrate the Festival of Tabernacles for seven days after you have gathered the produce of your threshing floor and your winepress. 14 Be joyful at your festival—you, your sons and daughters, your male and female servants, and the Levites, the foreigners, the fatherless and the widows who live in your towns. 15 For seven days celebrate the festival to the Lord your God at the place the Lord will choose. For the Lord your God will bless you in all your harvest and in all the work of your hands, and your joy will be complete.
