כְּרֵֽעַ־כְּאָ֣ח לִ֭י הִתְהַלָּ֑כְתִּי כַּאֲבֶל־אֵ֝֗ם קֹדֵ֥ר שַׁחֽוֹתִי׃
我來往行走，好像他們是我的朋友、我的兄弟一樣；我神色黯淡、屈身低頭，如同為母親哀悼的人。
Rashi
I walked about as though it were a friend or as though it were my own brother As though it were my brother or my friend; I walked about depressed because of their distress.
Rashi
as the mourning of a mother As a son who mourns for his mother or as a mother who mourns for her son.
