베레시트 (창세기) 37:25

ארחת means what the Targum says — A CARAVAN; this is called ארחת with reference to the travelers on the road (ארח) who compose it. וגמליהם נשאים AND THEIR CAMELS WERE BEARING etc. — Why does Scripture specially announce what they were laden with? It is to tell you how great is the reward of the righteous: it is not usual for Arabs to carry anything but naphta and itran (tar) which are evil-smelling, but for this one (Joseph, the righteous) it was specially arranged that they should be carrying fragrant spices so that he should not suffer from a bad odour (Genesis Rabbah 84:17). נכאת SPICERY — Every collection of many kinds of spices is called נכאת. So, too, (2 Kings 20:13) “and he showed them all the house of his נכתה which means the house where his spices were mixed. Onkelos translates it as meaning wax (perhaps an aromatic gum). צרי AND BALM — a resin that exudes from the wood of the balsam-tree: it is the נטף that is enumerated among the ingredients of the incense used in the Tabernacle (Exodus 30:34; cf. Keritot 6a). ולט AND LADANUM — This is called Lotos in the language of the Mishna. Our Rabbis have in treatise Niddah 8a explained that it is a vegetable root; it bears the name aristolochia (birthwort).

וַיֵּשְׁבוּ֮ לֶֽאֱכׇל־לֶ֒חֶם֒ וַיִּשְׂא֤וּ עֵֽינֵיהֶם֙ וַיִּרְא֔וּ וְהִנֵּה֙ אֹרְחַ֣ת יִשְׁמְעֵאלִ֔ים בָּאָ֖ה מִגִּלְעָ֑ד וּגְמַלֵּיהֶ֣ם נֹֽשְׂאִ֗ים נְכֹאת֙ וּצְרִ֣י וָלֹ֔ט הוֹלְכִ֖ים לְהוֹרִ֥יד מִצְרָֽיְמָה׃

And they sat down to eat bread: and they lifted up their eyes and looked, and, behold, a company of Yishme᾽elim came from Gil῾ad with their camels bearing gum balm and ladanum, going to carry it down to Miżrayim.
