Psalms 29:10 - Joseph Benson’s Commentary on the Old and New Testaments

The Lord sitteth upon the flood He moderates and rules the most abundant and violent effusions of waters which are sometimes poured from the clouds, and fall upon the earth, where they cause inundations which would do much mischief if God did not prevent it. And this may be mentioned as another reason why God's people praised and worshipped him in his temple; because, as he sendeth terrible tempests, thunders, lightnings, and floods, so he restrains and overrules them. But most interpreters refer this to Noah's flood, to which the word מבול, mabbul, here used, is elsewhere appropriated. And so the words may be rendered, The Lord sat upon the deluge; namely, in Noah's time, when, it is probable, those vehement and unceasing rains were accompanied with terrible thunders. Bishop Hare thus paraphrases the verse, “This is the same God who, in Noah's flood, sat as judge, and sent that destruction upon the earth.” And so the psalmist, having spoken of the manifestation of God's power in storms and tempests in general, takes an occasion to go back to that ancient and most dreadful example of that kind, in which the divine power was most eminently seen. And, having mentioned that instance, he adds, that as God had showed himself to be the King and the Judge of the world at that time, so he doth still sit, and will sit as King for ever, sending such tempests as it pleases him to send. And therefore his people have great reason to worship and serve him.
