(I hardly looked at the first page of this thread.)
PAA:
“
The Gemara relates that when Chizkiyahu was sick, he asked H’ to heal him based on a kal vachomer: ??? ?????? ??? ???? ??? ??? ??? ???? ????? ?? ??? ??? ??? ???? ?? ????? ???? ???? ????? ?? ??? ??? ????. Now if the kid had actually died then Chizkiyahu would have a kal vachomer even if his ??? ??? hadn’t done anything more than the Shunamite, beacause he was only asking to be healed, not to be resurrected.”
What exactly would that kal vachomer be?
“If you resurrected her son, you can surely heal me?”
That’s not a kal vachomer. A kal vachomer is as follows: When we see that something is done in a situation where there is little reason for it, then in a situation where there is more reason for it, all the more so should it be done! But “you have done a greater thing” is not a reason that “you should do a lesser thing” – it is merely proof that you are capabable of the lesser thing.
