אַתָּ֣ה מ֭וֹשֵׁל בְּגֵא֣וּת הַיָּ֑ם בְּשׂ֥וֹא גַ֝לָּ֗יו אַתָּ֥ה תְשַׁבְּחֵֽם׃
Thou rulest the proud swelling of the sea; When the waves thereof arise, Thou stillest them.
Rashi on Psalms
You humble them Heb. תשבחם, You humble them, and similarly, (Prov. 29:11): “but afterwards a wise man will quiet it (ושבחנה)”; and similarly (above 65:8): “Who humbles (משביח) the roaring of the seas.”
