The LORD sitteth upon the flood; yea, the LORD sitteth King for ever.
The conclusion applies to the case of God's people the lesson of confidence in the power of Yahweh their God, to be derived from the body of the psalm.
The Lord sitteth ... Chaldaic paraphrase, 'The Lord sat in judgment in the generation of the flood.' Compare the Vulgate [Dominus diluvium inhabitare facit], and Septuagint [kurios ton kataklusmon katoikiei].
Moreover, the Hebrew х mabuwl (H3999)] for "the flood" is exclusively applied to the Noachian deluge. Therefore, with Gejer, Hengstenberg, and Muis, translate, 'The Lord sat (so sit, Psalms 9:4; Psalms 9:7-8; Joel 3:12) AT lª- the flood (as the King and Judge, vindicating His people, and destroying the ungodly foe; whence follows the triumphant inference), and therefore the Lord will sit King forever.' The Hebrew article, too, points to a particular flood. As God delivered His people at the flood so will He now. God's people have no cause to fear, as having so Almighty and all-just a God on their side. Their foes now are what "the flood" was then (Isaiah 28:2; Isaiah 59:19; Jeremiah 46:7-8; Jeremiah 47:2). "The voice of the Lord is upon the (figurative) waters" now, as it was upon the literal waters then, and as it is upon the watery clouds in every thunder-storm even still (Psalms 29:3). If the English version be retained, still take "the flood" as primarily the Noachian deluge. "The Lord sitteth upon the flood," restraining it from overwhelming His people, as in the days of Noah.
Sitteth king. He hath for ever the power of commanding all the elements, being their King.
