We are on מכת שחין! This is the plague of puberty; just kidding, it is the plague of boils. ה׳ told משה how to help him start the plague, but they didn’t warn פרעה. The plan was for משה to throw פיח (soot, ashes) on פרעה and his advisors, and then ה׳ would give all of מצרים the present of שחין. Imagine going through another week of puberty! Even החרטומים של פרעה didn’t want to show their faces because even they couldn’t do the “dark magic” of שחין. Even פרעה was fed up and said the he would let the Jews go if משה stopped the plague. משה of course stopped שחין but פרעה did not let them go and (this is the miracle of life) his heart hardened😱😱😱😱😱.
