'Nothing' in the Bible

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

Then they said, “We will give it back and will require nothing from them; we will do exactly as you say.” So I called the priests and took an oath from them that they would do according to this promise.

Then he said to them, “Go, eat of the fat, drink of the sweet, and send portions to him who has nothing prepared; for this day is holy to our Lord. Do not be grieved, for the joy of the Lord is your strength.”
