'Nard' in the Bible

While he was at Bethany, in the house of Simon the leper, as he sat at the table, a woman came having an alabaster jar of ointment of pure nard -- very costly. She broke the jar, and poured it over his head.

Mary, therefore, took a pound of ointment of pure nard, very precious, and anointed the feet of Jesus, and wiped his feet with her hair. The house was filled with the fragrance of the ointment.
