Ever since I started learning about Judaism, I noticed that Israel’s emblem contains a 7 branch menorah, not the chanukiah (which everyone, including tons of Jews) call a menorah.
I understand that the 7 branch was in the Temple and depicted on the Arch of Titus. I’m considering buying a 7 branch menorah for my house.
I've found some wildly differing opinions online. Some say none are permitted, some say they're permitted provided that they are either non-metal (I see a bunch of enamel), some say all of the types I see online are permitted but simply cannot be lit. Which is the truth?
I also know Israel itself had a debate when the Knesset Menorah was given to it, but the chief rabbi at the time ultimately decided it was halachic.
