C. F. Keil and Franz Delitzsch on Esther 9:13

Est 9:13

Esther requested: “let it be granted to the Jews which are in Susa to do to-morrow also according to the decree of to-day (i.e., exactly as to-day), and let the ten sons of Haman be hanged upon the tree,” i.e., their dead bodies nailed on crosses - majoris infamiae causa, according to Hebrew and Persian custom; comp. Deu 21:22 and the explanation of Ezr 6:11. On the motive for this request, see above, p. 194.
