No mention of the colour blue in Hebrew texts!
Is this true?

[Shah-Jehan]

Yeah, I heard the flag of Israel is actually just plain white to Jews :laugh:

[Longbowman]

What's blue?

(actually Jews used to have to wear blue tassels on their clothes, true story. It is certainly in the bible)

[Trogdor]

So...what is the point of this thread exactly?
