Leviticus 23
40 Ref You shall take on the first day the fruit of goodly trees, branches of palm trees, and boughs of thick trees, and willows of the brook; and you shall rejoice before Yahweh your God seven days.
41 Ref You shall keep it a feast to Yahweh seven days in the year: it is a statute forever throughout your generations; you shall keep it in the seventh month.
42 Ref You shall dwell in booths seven days. All who are native-born in Israel shall dwell in booths,
43 Ref 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 Yahweh your God.'"
