כִּלָּ֤ה יְהוָה֙ אֶת־חֲמָת֔וֹ שָׁפַ֖ךְ חֲר֣וֹן אַפּ֑וֹ וַיַּצֶּת־אֵ֣שׁ בְּצִיּ֔וֹן וַתֹּ֖אכַל יְסוֹדֹתֶֽיהָ׃ (ס)
גאָט האָט אױסגעלאָזט זײַן כּעס, אױסגעגאָסן זײַן גרימצאָרן; און ער האָט אָנגעצונדן אַ פֿײַער אין צִיוֹן, און עס האָט פֿאַרצערט אירע גרונטפֿעסטן.
Tze'enah Ure'enah
“Completed” [4:11]. The Holy One has completed his anger that He contemplated for a long time. Now He has poured out His wrath and ignited the fire on Zion. This has burned the ground completely.
Rashi
Adonoy spent His wrath. Which burned in Him for many years.17God’s fury is compared to a ‘consuming fire’ as in Eichah 2:3 above; also see Devorim 4:24. He now spent it when He avenged Himself upon them.
