Leviticus 23:38-40

Young's Literal Translation

³⁸ apart from the sabbaths of Jehovah, and apart from your gifts, and apart from all your vows, and apart from all your willing-offerings, which ye give to Jehovah.

³⁹ `Only -- in the fifteenth day of the seventh month, in your gathering the increase of the land, ye do keep the feast of Jehovah seven days; on the first day [is] a sabbath, and on the eighth day a sabbath;

⁴⁰ and ye have taken to yourselves on the first day the fruit of beautiful trees, branches of palms, and boughs of thick trees, and willows of a brook, and have rejoiced before Jehovah your God seven days.
