When he uttereth his voice
Declares his will and pleasure, issues out his commands; or when he thunders, for thunder is his voice, ( Job 37:2-5 ) ( 40:9 ) : 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 1 Kings 18:44 ) . 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.
