'Rubies' in the Bible

Corals and pearl are not remembered, The acquisition of wisdom is above rubies.

Precious she is above rubies, And all thy pleasures are not comparable to her.

For better is wisdom than rubies, Yea, all delights are not comparable with it.

Substance, gold, and a multitude of rubies, Yea, a precious vessel, are lips of knowledge.

A woman of worth who doth find? Yea, far above rubies is her price.

Purer were her Nazarites than snow, Whiter than milk, ruddier of body than rubies, Of sapphire their form.
