Leviticus 23:40-41

⁴⁰And ye shall take to you in the first day fruits of the fairest tree(s), and the branches of palm trees, and the branches of a thick-boughed tree, and sallows of the running stream, and ye shall be glad before your Lord God; (And on the first day ye shall take the fruits of the fairest trees, and the branches of palm trees, and the branches of thick-boughed trees, and of willows from the banks of the streams, and ye shall rejoice before the Lord your God;)

⁴¹and ye shall hallow his solemnity seven days in the year; it shall be a lawful thing everlasting in your generations. In the seventh month ye shall hallow the feast days, (and ye shall dedicate this Feast to honour the Lord for seven days each year; this shall be an everlasting law for all your generations. In the seventh month ye shall dedicate these feast days,)
