Leviticus 23:41-43

King James Version

⁴¹ And ye shall keep it a feast unto the Lord seven days in the year. It shall be a statute for ever in your generations: ye shall celebrate it in the seventh month.

⁴² Ye shall dwell in booths seven days; all that are Israelites born shall dwell in booths:

⁴³ That your generations may know that I made the children of Israel to dwell in booths, when I brought them out of the land of Egypt: I am the Lord your God.
