הִשְׁבַּ֥תָּ מִטְּהָר֑וֹ וְ֝כִסְא֗וֹ לָאָ֥רֶץ מִגַּֽרְתָּה׃
你使他的光輝止息，把他的王位推倒在地。
Rashi
You have brought an end to his shining Heb. מטהרו, his shining, as צהרים, noon, is translated טהרא, and like (Exod. 24:10): “and like the appearance of the heaven for splendor (לטהר).”
Rashi
You have cast down to the earth Heb. מגרת. You have humbled and destroyed. Every expression of bending down is, in Targum Jonathan, מגר.
