'Sad' in the Bible

And he asked the court officials of Pharaoh that [were] with him in the custody of his master's house, "Why [are] your faces sad today?"

And she said, "May your female slave find favor in your sight." Then the woman went on her way and ate [something], and {her face did not look sad any longer}.

It happened in the month of Nisan, in the twentieth year of King Artaxerxes, when wine was before him, I carried the wine and gave it to the king. And I had never been sad before the king.

So the king said to me, "Why is your face sad since you are not sick? This is nothing but sadness of the heart." And I was very much afraid.

I said to the king, "May the king live forever! Why should my face not be sad when the city of my ancestors' burial site is ruined and her gates are consumed by fire?"

Even in laughter, a heart may be sad, and the end of joy [may be] grief.
