Tossefta sur Rois 1 10:27

וַיִּתֵּ֨ן הַמֶּ֧לֶךְ אֶת־הַכֶּ֛סֶף בִּירוּשָׁלִַ֖ם כָּאֲבָנִ֑ים וְאֵ֣ת הָאֲרָזִ֗ים נָתַ֛ן כַּשִּׁקְמִ֥ים אֲשֶׁר־בַּשְּׁפֵלָ֖ה לָרֹֽב׃

Le roi rendit l’argent, à Jérusalem, aussi commun que les pierres, et les cèdres aussi nombreux que les sycomores de la vallée.

Tosefta Sheviit

What is the "valley" that is in the Galilee? That such as Ginosar and that which is adjacent to it. Rabbi Shimon ben Elazar says, what is the mountain that is on the "other side of the Jordan" (Sheviit 9:2)? That such as Harim and such as Gibor Gadur and that which is adjacent to it. Its "plains"? "Heshbon and all its towns in the Tableland: Dibon, Bamoth-baal, Beth-baal-meon" (Josh. 13:17, JPS tr.). Its "valleys"? That such as Beit Namra (Josh. 13:27), Ramata, and that which is adjacent to it. Rabbi Shimon ben Gamaliel says, a sign for "mountains" is ash trees; a sign for "valleys" is date palms; a sign for "rivers" is reeds; a sign for plains is sycamores. And even though there is no proof of the matter [in Scripture], there is at least a hint of the matter (1 Kings 10:27): "[Solomon] made cedars as plentiful as sycamores in Shephlah"*i.e., although "Shephlah" is the proper name of a location in 1 Kings 10:27, the literal meaning of that word (שפלה) is "plain").
