What is the "Azkarasah" referring to?
Rashi: It (is a Lashon of burning - Rashi, in Tehilim, 29:9, and) refers to the Kometz. 1
Since it reminds Hashem (Kevayachol) of the owner for the good.
Why did the Torah not mention the Soles, the Shemen and the Levonah in the way that it did above in Pasuk 2 and later, in 6:8?
Oznayim la'Torah: Because, having just included various Menachos that do not contain either Soles or Shemen of Levonah in the Din of Hagashah, it stated simplty "es Azkarasah" to include them as well in the Din of Haktarah.
With what does the Kohen take the Kometz?
Menachos, 61a: With his fist - which we learn via a Gezeirah Shavah 'Veheirim" "Veheirim" from Tzav, 6:8.
Why does the Torah write "Veheirim min ha'Minchah" and not simply " Veheirim Mimenah"
