'Sweet' in the Bible

For we are a sweet odour of Christ to God, in the saved and in those that perish:

But I have all things in full supply and abound; I am full, having received of Epaphroditus the things sent from you, an odour of sweet savour, an acceptable sacrifice, agreeable to God.

Does the fountain, out of the same opening, pour forth sweet and bitter?

Can, my brethren, a fig produce olives, or a vine figs? Neither can salt water make sweet water.

And I went to the angel, saying to him to give me the little book. And he says to me, Take and eat it up: and it shall make thy belly bitter, but in thy mouth it shall be sweet as honey.

And I took the little book out of the hand of the angel, and ate it up; and it was in my mouth as honey, sweet; and when I had eaten it my belly was made bitter.
