Because they are both wrong. His name is Tzemach. Zecharia does not
translate the name.
Rashi and Ibn Ezra say that this is Zerubavel. Rashi further
explains that though some say that this is Mashiach, this refers to
second Temple.
"U'MiTachtav Yitzmach" Rashi says he will grow from the seed of
royalty. Radak says he will grow from Jerusalem. Metzudat David
says that Mashiach will grow from his (Zerubavel's) seed.
Anyway, tzemach, the word, not proper noun, means plant
Shoshanna
In Zechariah 6:12 The Name Tsemach translates Branch, in Greek it
translates anatole, which means rising of the sun. can anyone explain
why?
