קָצַ֣פְתִּי עַל־עַמִּ֗י חִלַּ֙לְתִּי֙ נַחֲלָתִ֔י וָאֶתְּנֵ֖ם בְּיָדֵ֑ךְ לֹא־שַׂ֤מְתְּ לָהֶם֙ רַחֲמִ֔ים עַל־זָקֵ֕ן הִכְבַּ֥דְתְּ עֻלֵּ֖ךְ מְאֹֽד׃
I was wroth with My people, I profaned Mine inheritance, And gave them into thy hand; Thou didst show them no mercy; Upon the aged hast thou very heavily Laid thy yoke.
