וְאַתָּ֥ה בֶן־אָדָ֖ם הֵֽאָנַ֑ח בְּשִׁבְר֤וֹן מָתְנַ֙יִם֙ וּבִמְרִיר֔וּת תֵּֽאָנַ֖ח לְעֵינֵיהֶֽם׃
Sigh therefore, thou son of man; with the breaking of thy loins and with bitterness shalt thou sigh before their eyes.
Read halakhic rulings (Jewish law) on Ezekiel 21:11: and classical halakhic sources.
