For he commandeth - Hebrew, "he says;" that is, He speaks the word, and it is done. The mere expression of his will raises up the storm, and throws the sea into commotion.
And raiseth the stormy wind - Margin, as in Hebrew, "Maketh to stand." The "stormy wind" is literally, the wind of the tempest.
Which lifteth up the waves thereof - The waves of the ocean. The wind seems to take them up, and lift them on high.

For he commandeth - And what less than the command of God can raise up such winds as seem to heave old Ocean from his bed?

For he commandeth, and raiseth the stormy wind,.... Winds are not raised by men, nor by devils, nor by angels, but by the Lord himself; who has created them, holds them in his fist, brings them out of his treasures, and sends them forth to do his will; if he speaks the word, gives but the order, a storm arises at once, and executes what he pleases, Psalm 148:8.
Which lifteth up the waves thereof; that is, the waves of the sea; it comes down into it, and causes surges; which rise above the ship, and sometimes cover it, and ready to sink it; yea, even they are lifted up to the heavens, as it follows.

waves thereof--literally, "His waves" (God's, Psalm 42:7).
