Rashi: Chananyah, Misha'el and Azaryah.

Radak: The other Kohanim.

Malbim: Chachamim, his Talmidim.

Horiyos 13b: A Kohen Gadol precedes a prophet ? he is mentioned before his colleagues." Do not say that his colleagues are commoners. They are "Anshei Mofes."

Horiyos 13b: They are prophets.

Rashi: They are men proper for miracles to be done for them. Also for them (Chananyah, Misha'el and Azaryah), a miracle was done (Sanhedrin 93a).

Malbim: They are proper for Nevu'ah.

Rashi: Now, Zerubavel Pachas Yehudah, was small in Chatzer ha'Melech. I will make grandeur sprout for him. I will give to him grace in the eyes of the king, to accede to his request to build the Bayis and the [wall of the] city, like it says in Ezra "Divrei Nechemyah ben Chachalyah ¹ "; he is Zerubavel, like it says in Sanhedrin (37b).

Radak #1: This is Zerubavel. Even though he already came, I will increase his level and make his grandeur sprout, like vegetation that grows. So it says below "Hine Ish Tzemach Shmo umi'Tachtav Yitzmach u'Vanah Es Heichal Hashem" (6:12). And so said Chagai "Ekachacha Zerubavel?" (2:23).

Radak #2, Targum Yonasan: Tzemach is Melech ha'Mashi'ach. Even though I bring this salvation, I will bring another salvation, greater than it, when I will bring Avdi Tzemach. They also expounded (Eichah Rabah 1:51) that Mashi'ach's name is Menachem; its Gematriya is the same as that of Tzemach (138). Malbim ? he is called Tzemach, for now the shoot from the stump of Yishai was cut off and it is hidden, buried in the ground. It is like a seed buried deep in the ground. It will sprout in its time, and be revealed. The name Zerubavel hints to this ? he was seeded in Bavel. I.e. he is like a seed in the ground. It will sprout at the time of the Ge'ulah.
