Comentario sobre Exodo 15:7

וברב גאנך AND THROUGH THE GREATNESS OF THINE EXCELLENCY: if the hand alone crushes the spirit of the enemy, then when He raises it aloft IN THE GREATNESS OF HIS EXCELLENCY surely then HE WILL OVERTHROW THEM THAT RISE UP AGAINST HIM; and if through the greatness of His excellency alone His enemies are overthrown, how much more sure is it that when HE SENDETH FORTH THE FIERCENESS OF HIS WRATH against them IT WILL CONSUME THEM].

וברב גאונך תהרוס קמיך, "And in the greatness of Your glory You destroy those who rise up against You." The verse tells us that G'd performs miracles to underline that it is He who destroys His opponents. In order that we should not think that G'd has to extend Himself in order to accomplish this, the Israelites added: "even when You merely send forth Your wrath they already turn to straw."

תהרס קמיך, the word תהרס describes the “removal,” הסרה of something, lowering or moving something sideways from where it used to be. One example of the use of the word in this sense is found in Exodus 19,21 פן יהרסו אל ה', “so that they should not move closer to Hashem, etc.” In that instance, the purpose would have been to draw close in order to see better. Psalms 52,7 also employs the word in this sense.
