Zechariah #6 (Chapter 4)
The haftarah for Parshat Behaalotecha (and Shabbat Chanukah) ends with a description of Zechariah's vision of the menorah.
The symbolism of the stone with seven eyes that will serve as the cornerstone of the Bet HaMikdash. After showing Zechariah the cornerstone, the angel shows him the vision of the Menorah and is surprised that Zechariah doesn't know what it is.
The explanation of the Malbim of the vision of the cornerstone with seven eyes, Zechariah's vision of the Menorah and the relationship between the two.
Both Zechariah and Betzalel had difficulty understanding the menorah.
