'Nard' in the Bible

While He was in Bethany [as a guest] at the home of Simon the leper, and reclining at the table, a woman came with an alabaster vial of very costly and precious perfume of pure nard; and she broke the vial and poured the perfume over His head.

Then Mary took a pound of very expensive perfume of pure nard, and she poured it on Jesus’ feet and wiped His feet with her hair; and the house was filled with the fragrance of the perfume.
