Who did Zecharyah address?
Rashi: The angel that showed all of this to him. He was riding on a red horse 1 .
Radak (10) holds that they are not the same. He addressed the former, and also the latter answered him. (PF)
What is the question "Mah Eleh"?
Malbim: What do they signify?
What is the meaning of "ha'Dover Bi"?
Radak: He is the one who brought "Devar Hashem El Zecharyah" (7).
Why did he say "I will show you?" He will tell him!
Radak #1: "Ar'eka" is like 'I will make you hear.' Sight is applied to other senses, for it is the strongest sense ? "v'Chol ha'Am Ro'im Es ha'Kolos (Shemos 20:15), "Re'eh Rei'ach Bni" (Bereishis 27:27).
Radak #2: "Ar'eka" applies to the other vision that he showed to him of four horns (2:1). This vision explains that one 1 , even though Zecharyah did not understand it until the angel explained it to him.
Malbim: The other visions will explain this one.
