פירוש על שמות 9:11

AND THE MAGICIANS COULD NOT STAND BEFORE MOSES. They were ashamed, and confounded, and covered their heads²⁰⁷Jeremiah 14:3. since they were full of boils and could not rescue themselves. Therefore they made no appearance in the royal palace, nor did they appear before Moses in the streets. And so they were imprisoned in their homes.

ולא יכלו החרטומים לעמוד, “and the sorcerers could no longer stand before Moses, etc.” This is a description of the embarrassment of the sorcerers at their impotence, so that they withdrew to their private quarters so as not to have to face any hostile or disrespectful audience.

V. 11. Die Schriftkundigen waren wahrscheinlich auch Ärzte. Diese die Arzneikunst herausfordernde Plage traf sie daher zuerst und — wie es scheint, da sie sonst ja nicht mit Mosche zusammen kamen — sofort, nachdem der Ruß ausgestreut worden war.
