'Sorrow' in the Bible

Then, after hearing these words, for some days I gave myself up to weeping and sorrow, seated on the earth; and taking no food I made prayer to the God of heaven,

And the king said to me, Why is your face sad, seeing that you are not ill? this is nothing but sorrow of heart. Then I was full of fear;

And Nehemiah, who was the Tirshatha, and Ezra, the priest and scribe, and the Levites who were the teachers of the people, said to all the people, This day is holy to the Lord your God; let there be no sorrow or weeping; for all the people were weeping on hearing the words of the law.
