There appears to be a conflict between what G-d says should be thrown skyward for the plague of boils (שחין) and what was actually done.
In Shemot 9:8, when G-d is saying what should occur, it says:
וזרקו משה השמימה לעיני פרעה
They shall throw Moses towards the sky before Pharaoh's eyes
But, when Moses appears before Pharaoh, Shemot 9:10 it says:
ויקחו את פיח הכבשו ויעמדו לפני פרעה ויזרק אתו משה השמימה...
They took the oven soot, stood before Pharaoh. They threw him skywards...
I assume that the word "him" in the above verse refers to Pharaoh, and they (Moses and Aharon) threw him skyward.
I'm puzzled here. Why does G-d command that Moses should be thrown skyward, but when they actually do it, Moses disobeys G-d's command and throws Pharaoh, instead?
