'Pure' in the Bible

His head is pure gold, his hair is wavy, black like a raven.

His legs are pillars of marble set on bases of pure gold. His appearance is like Lebanon, choice like its cedars.

but my dove, my perfect one, is unique. She's unique to her mother, she's pure to the one who gave birth to her. Young women see her and call her blessed, queens and mistresses praise her.
