John Gill

Or speak to the earth, and it shall teach thee,.... Or ask "a sprig of the earth" (n), any shrub, or tree, or whatsoever grows out of it, and they will all unite in this doctrine, that they are raised and preserved by the power of God, and are so many instances of his wisdom, power, and goodness: and the fishes of the sea shall declare unto thee; as mute as they are, they will proclaim this truth, that God is the mighty Maker and wise Disposer of them. (n) "virgultum terrae", Pagninus, Schmidt; so Drusius and Michaelis.
