Lamentations 2:8 Halakhah

חָשַׁ֨ב יְהוָ֤ה ׀ לְהַשְׁחִית֙ חוֹמַ֣ת בַּת־צִיּ֔וֹן נָ֣טָה קָ֔ו לֹא־הֵשִׁ֥יב יָד֖וֹ מִבַּלֵּ֑עַ וַיַּֽאֲבֶל־חֵ֥ל וְחוֹמָ֖ה יַחְדָּ֥ו אֻמְלָֽלוּ׃ (ס)

The LORD hath purposed to destroy The wall of the daughter of Zion; He hath stretched out the line, He hath not withdrawn His hand from destroying; But He hath made the rampart and wall to mourn, They languish together.
