'Savor' in the Bible

Ye are the salt of the earth: but if the salt have lost its savor, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out and trodden under foot of men.

Salt therefore is good: but if even the salt have lost its savor, wherewith shall it be seasoned?

But thanks be unto God, who always leadeth us in triumph in Christ, and maketh manifest through us the savor of his knowledge in every place.

For we are a sweet savor of Christ unto God, in them that are saved, and in them that perish;

to the one a savor from death unto death; to the other a savor from life unto life. And who is sufficient for these things?
