Midrash for Exodus 10:9

Another interpretation (of Exod. 15:25): AND THE LORD SHOWED HIM A TREE. What was it?⁶¹Tanh., Exod. 4:24; Mekhilta de Rabbi Ishmael, Wayassa‘ 1; Exod. R. 50:3. R. Joshua says: It was an olive tree; R. Nehemiah says: A willow tree. Some say: The roots of a fig tree; and others say: The roots of a pomegranate, since there is nothing as bitter as those. But the sages say: It was ivy⁶²Gk.: rhododaphne (“rose laurel” or perhaps “rhododendron”). wood, and there is nothing as bitter as that. R. Ishmael the son of R. Johanan ben Baroqah said: See how great are the miracles of the Holy One! <Those of> flesh and blood cure the bitter with the sweet, but the Holy One cures the bitter with the bitter.⁶³See below, Exod. 10:9, and the note there. Thus it is stated (in Jer. 30:17): [FOR I WILL RESTORE HEALTH TO YOU]: AND I WILL HEAL YOU OF YOUR WOUNDS, SAYS THE LORD. By whatever means he wounds he heals. The Holy One told Moses to put something sour into something sour for it to become sweet thereby. Similarly it is written (in II Kings 2:21): SO <ELISHA> WENT OUT TO THE SPRING OF WATER, THREW SALT IN IT,…⁶⁴The biblical text indicates that there is no lacuna here. AND SAID: THUS SAYS THE LORD: I HAVE HEALED <THIS> WATER. Similarly (in Is. 38:21): AND ISAIAH SAID: LET THEM TAKE A CAKE OF FIGS <AND APPLY IT TO THE BOIL, AND HE WILL LIVE>. Is it not a fact that, when one puts fig juice on the flesh, it is immediately consumed? <This exception,> however, <was> in order to perform a miracle.
