'Nard' in the Bible

While He was in Bethany at the house of Simon who had a serious skin disease, as He was reclining at the table, a woman came with an alabaster jar of pure and expensive fragrant oil of nard. She broke the jar and poured it on His head.

Then Mary took a pound of fragrant oil—pure and expensive nard—anointed Jesus’ feet, and wiped His feet with her hair. So the house was filled with the fragrance of the oil.
