The Greek noun muron means ointment, perfume, or aromatic oil. It was a precious, costly substance — a blend of myrrh and other spices used for anointing kings, priests, the dead, and honored guests. The most famous New Testament uses involve women who anointed Jesus, foreshadowing his burial.
Muron is the word of costly devotion. When the woman at Bethany broke her alabaster jar of muron over Jesus (Mark 14:3; John 12:3), the perfume filled the room — a lavish, irreversible gift that Jesus defended as preparation for his burial and as a memorial act. The Nicodemus and women at the tomb also brought muron. Anointing with oil carries royal, priestly, and burial significance — all converging in Jesus, who is Prophet, Priest, and King.
