Translation:They are five people but they have six opinions.
I think there is a Serbian proverb that goes something like "two Russians - a choir, one Serb - three political parties".
I think it's a Rabbinic saying - I was listening to a Rabbi teaching Hebrew on youtube and he said something like this, that you can put five rabbis in a room to discuss the Torah and you'll get six different opinions, meaning no consensus, just a lot of discussion and differing views. Presbyterians are the same way! :)
