Hassidout sur Les Psaumes 145:5

הֲ֭דַר כְּב֣וֹד הוֹדֶ֑ךָ וְדִבְרֵ֖י נִפְלְאוֹתֶ֣יךָ אָשִֽׂיחָה׃

La splendeur de ta glorieuse majesté, le détail de tes merveilles, voilà ce que je veux exposer.

Kedushat Levi

Followers of the Ari z’al are familiar with his writing on ‎the words ‎וימלוך....וימת‎, “he reigned…..he died;” he saw in this ‎formula used in the Bible a summary of a period during which ‎certain kings ruled, concerning which the author of that chapter ‎in the Bible wishes to convey that once a king begins to display ‎arrogance, i.e. he perceives himself as a ruler, he is already as if ‎dead.‎
The act of elevating oneself is tantamount to the act of killing ‎oneself. When David characterizes G’d’s “Kingdom” with the ‎words: ‎מלכותך מלכות כל עולמים‎, “Your Kingdom is an everlasting ‎Kingdom,” (psalms 145,5) repeating the word ‎מלכות‎, he speaks of ‎different eras. The era of which Isaiah had spoken when he ‎described the nations of the world eagerly joining the Jewish ‎people in accepting the rule of Heaven, is when that Kingdom will ‎become eternal and irrevocable. David hints that this came about ‎precisely because G’d allowed for opposition to His rule until ‎mankind matured.‎
