3 Bible Verses about Sweetness

Does a spring pour forth from the same opening sweet water and bitter?

And I went to the angel and told him to give me the little book. And he said to me. "Take it, and eat it up; it will make your belly bitter, but in your mouth it will be as sweet as honey."

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