וְ֭אוּלָם הַר־נוֹפֵ֣ל יִבּ֑וֹל וְ֝צ֗וּר יֶעְתַּ֥ק מִמְּקֹמֽוֹ׃
Ngunit ang bundok na gumuguho ay tunay na nadudurog, at ang bato ay naaalis sa kinalalagyan nito.
Rashi
And surely the falling mountain gives forth produce The height of a falling mountain will give forth produce. It will produce dust, and there will be hope of deriving benefit from it. and the rock that moves from its place will also give forth produce. This is an expression of grain.
Malbim
Malbim notes that 'naturalists have agreed that mountains grow'. He is perhaps referring to the hypothesis of a geological uplifting force that balances erosion first proposed by Hutton in 1785 and popularized half a century later by Lyell.
