When he uttereth his voice,.... Declares his will and pleasure, issues out his commands; or when he thunders, for thunder is his voice, Job 37:2:
there is a multitude of waters in the heavens; they are covered with clouds, and these clouds full of water; which is brought about by the following means:
and he causeth the vapours to ascend from the ends of the earth; from the north and south, as Kimchi observes from the philosophers; or from all parts of the earth, the most distant, and particularly from the sea, the border of the earth, from whence clouds arise, being exhaled by the sun; see 1 Kings 18:43.
He maketh lightnings with rain; which very often go together, and the one makes way for the other, Job 28:26, though they are so opposite one to another:
and bringeth forth the wind out of his treasures; the caverns of the earth, or his fists, in which he holds it, Proverbs 30:4 and lets its loose at his pleasure; he has plenty of it in reserve; he is Lord over it; he sends it forth when he pleases, and it fulfils his will and his word.
