Adam Clarke on Zechariah 4:14

These are the two anointed ones - Joshua, the high priest; and Zerubbabel the governor. These are anointed - appointed by the Lord; and stand by him, the one to minister in the ecclesiastical, the other in the civil state.

Probably we may not be able to comprehend the whole of this hieroglyphical vision; for even the interpreting angel does not choose to answer the questions relative to this, which were put to him by the prophet. See Zac 4:4, Zac 4:11. But though the particulars are hard to be understood; yet the general meaning has, I hope, been given.
