'Wool' in the Bible

For when every commandment in the Law had been read by Moses to all the people, he took the blood of the calves and goats [which had been sacrificed], together with water and scarlet wool and with a bunch of hyssop, and he sprinkled both the scroll itself and all the people,

His head and His hair were white like white wool, [glistening white] like snow; and His [all-seeing] eyes were [flashing] like a flame of fire [piercing into my being].
