Leviticus 23
39 Ref "'So on the fifteenth day of the seventh month, when you have gathered in the fruits of the land, you shall keep the feast of Yahweh seven days: on the first day shall be a solemn rest, and on the eighth day shall be a solemn rest.
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.'"
