הֶהָרִ֥ים וְכָל־גְּבָע֑וֹת עֵ֥ץ פְּ֝רִ֗י וְכָל־אֲרָזִֽים׃
בערג און אַלע הײכן, פֿרוכטבײמער און אַלע צעדערן;
Ibn Ezra
ההרים The mountains. I derive הרים from הרה to conceive, as I shall explain in the Book of Psalms (148:9).21In his commentary on Ps. 148:9, Ibn Ezra says that the mountains are pregnant (הרה) with all kinds of metals; therefore they are called הָרִים.
