'Odor' in the Bible

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: and the house was filled with the odor of the ointment.

and walk in love, even as Christ also loved you, and gave himself up for us, an offering and a sacrifice to God for an odor of a sweet smell.

But I have all things, and abound: I am filled, having received from Epaphroditus the things that came from you, and odor of a sweet smell, a sacrifice acceptable, well-pleasing to God.
