The table below presents an aligned extract of verses or verselets in Ex09-08. Both verses/verselets discuss the 6th plague, the furnace ashes. The alignment justifies the Rashi comment that: There were a variety of miracles here. Moses and Aaron took handfuls of ashes but 1st) only Moses threw it upward and 2nd) with only one hand 3rd) Although it was 2 handfuls of ashes it spread over all of Egypt

Advanced Rashi:In the table above we have physically aligned the verse phrases. In fact this is the reason we call this the alignment method since the physical alignment neatly shows the verse differences which drive the various Rashi comments. Corresponding to the 4 alignments shown above we have the following 4 comments:
1. Although Moses and Aaron took handfuls Moses alone threw the two handfuls
2. Although Moses and Aaron each took a handful (so 2 handfuls) Moses alone threw it. Now throwing typically is done with one hand. So Moses' one hand held the 2 handfuls
3. Although there were two handfuls of ash, it sufficed to spread dust over all of Egypt
4. Although they threw ash it became dust.

Rashi only mentions 3 of the miracles. He does not mention that the ash became dust. This is typical of the alignment method - when performing the alignment further differences not all enumerated in Rashi are discovered. Notice also that the eruption of boils (mentioned later on in the verses) from the furnace ash is still an additional miracle.
