Leviticus 23:40

פרי עץ הדר THE FRUIT OF THE TREE HADAR — a tree the wood of which (עץ) has the same taste as its fruit (פרי) (Sifra, Emor, Chapter 16 4; Sukkah 35a). הדר — It is called הדר because it is the tree whose fruit remains (הַדָּר) on the tree from one year to another (several years) — and this is the “Ethrog”. כפת תמרים A BRANCH OF PALM TREES — The word כפת is written defective (without ו, not כפות) to intimate that only one branch is intended (Sukkah 32a). וענף עץ עבת AND BOUGHS OF THE TREE עבת — i. e. of a tree whose boughs are, as it were, plaited (intertwined one with another) like ropes (עבתות) and cords; this is the myrtle plant which is indeed formed as a plait (three leaves issuing from one point of the branch and covering it) (Sukkah 32b).

וּלְקַחְתֶּ֨ם לָכֶ֜ם בַּיּ֣וֹם הָרִאשׁ֗וֹן פְּרִ֨י עֵ֤ץ הָדָר֙ כַּפֹּ֣ת תְּמָרִ֔ים וַעֲנַ֥ף עֵץ־עָבֹ֖ת וְעַרְבֵי־נָ֑חַל וּשְׂמַחְתֶּ֗ם לִפְנֵ֛י יְהֹוָ֥ה אֱלֹהֵיכֶ֖ם שִׁבְעַ֥ת יָמִֽים׃

And you shall take for yourselves on the first day the fruit of the tree hadar, branches of palm trees, and the boughs of thick leaved trees, and willows of the brook; and you shall rejoice before the Lord your God seven days.
