'Ointment' in the Bible

and it was Mary who did anoint the Lord with ointment, and did wipe his feet with her hair, whose brother Lazarus was ailing --

Mary, therefore, having taken a pound of ointment of spikenard, of great price, anointed the feet of Jesus and did wipe with her hair his feet, and the house was filled from the fragrance of the ointment.

'Wherefore was not this ointment sold for three hundred denaries, and given to the poor?'
