'Sad' in the Bible

And it came to pass in the month Nisan, in the twentieth year of Artaxerxes the king, that wine was before him, and I took up the wine and gave it to the king. Now, I had never been sad in his presence.

And the king said to me, Why is thy face sad, seeing thou art not sick? this is nothing else but sadness of heart. And I was very sore afraid.

And I said to the king, Let the king live for ever! Why should not my countenance be sad, when the city, the place of my fathers' sepulchres, lies waste, and its gates are consumed with fire?
