'Pure' in the Bible

“His head is like gold, pure gold;His locks are like clusters of datesAnd black as a raven.

“His legs are pillars of alabasterSet on pedestals of pure gold;His appearance is like LebanonChoice as the cedars.

But my dove, my perfect one, is unique:She is her mother’s only daughter;She is the pure child of the one who bore her.The maidens saw her and called her blessed,The queens and the concubines also, and they praised her, saying,

‘Who is this that grows like the dawn,As beautiful as the full moon,As pure as the sun,As awesome as an army with banners?’
