'Fragrance' in the Bible

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.

But thanks be to God, who always leads us in triumph in Christ, and through us spreads and makes evident everywhere the sweet fragrance of the knowledge of Him.

For we are the sweet fragrance of Christ [which ascends] to God, [discernible both] among those who are being saved and among those who are perishing;

to the latter one an aroma from death to death [a fatal, offensive odor], but to the other an aroma from life to life [a vital fragrance, living and fresh]. And who is adequate and sufficiently qualified for these things?

and walk continually in love [that is, value one another—practice empathy and compassion, unselfishly seeking the best for others], just as Christ also loved you and gave Himself up for us, an offering and sacrifice to God [slain for you, so that it became] a sweet fragrance.
