The wise in heart is called intelligent, and the sweetness of the lips increaseth learning.

Ointment and perfume rejoice the heart; and the sweetness of one's friend is the fruit of hearty counsel.

And he said unto me, Son of man, cause thy belly to eat, and fill thy bowels with this roll which I give thee. And I ate, and it was in my mouth as honey for sweetness.
