Zech 3:1-10 Zechariah has a vision of Joshua, the High Priest, standing before an angel of the LORD in the court of heaven. Satan, "the accuser", brings an accusation against Joshua, but the LORD defends him.
The angel of the LORD tells Joshua, “I have taken away your sin from you, and I am giving you beautiful fine clothes… If you do as I tell you and serve me, you will be in charge of my Temple and my courtyards.” (Zechariah 3:4-6)
The LORD's angel talks about the future: "I am going to bring my servant called the Branch... And in one day I will take away the sin of this land." (Zechariah 3:8-9)
Zech 4:1-14 Zechariah has a vision of a gold lampstand with seven lamps (a menorah as used in the Temple) and an olive tree on each side of it.
The angel explains the meaning of the vision: The lamps represent “the seven eyes of the LORD, which look back and forth across the earth” (Zechariah 4:10) while the two olive trees stand for Zerubbabel (the Governor) and Joshua (the High Priest) - "the two who have been appointed to serve the LORD.” (Zechariah 4:14)

Zech 6:1-8 Zechariah has a vision of four chariots that represent the four winds. The four chariots inspect the nations of the earth and report back to the LORD.
