כִּ֤י כָל־רֹאשׁ֙ קָרְחָ֔ה וְכָל־זָקָ֖ן גְּרֻעָ֑ה עַ֤ל כָּל־יָדַ֙יִם֙ גְּדֻדֹ֔ת וְעַל־מָתְנַ֖יִם שָֽׂק׃
For every head is bald, And every beard clipped; Upon all the hands are cuttings, And upon the loins sackcloth.
Read halakhic rulings (Jewish law) on Jeremiah 48:37: and classical halakhic sources.
