'Red' in the Bible
Come now, and let us have an argument together, says the Lord: how may your sins which are red like blood be white as snow? how may their dark purple seem like wool?
Who is this who comes from Edom, with blood-red robes from Bozrah? he whose clothing is fair, stepping with pride in his great strength? I whose glory is in the right, strong for salvation.
Why is your clothing red, and why are your robes like those of one who is crushing the grapes?
I have been crushing the grapes by myself, and of the peoples there was no man with me: in my wrath and in my passion, they were crushed under my feet; and my robes are marked with their life-blood, and all my clothing is red.
