Zechariah 1:8 Commentary: Rashi & Radak

I saw tonight Our Sages explained [this phrase as] they explained [it] in the Aggadah of the chapter entitled “Helek” (Sanh. 93a), but the sequence of the chapter and the language do not fit it.

"I saw by night." The visions of Zechariah are very obscure, like those of Daniel, but the visions of the other prophets are not so ; the reason is, that the power of prophecy had been gradually exhausting from the days of the captivity ; therefore, they did not make their words clear, and did not understand the visions as they were. He says, " I saw by night," i. e., in the visions of the night I saw this vision, in which I beheld -

and behold! A man an angel.
