'Sad' in the Bible

Then Elkanah her husband said to her, “Hannah, why do you weep and why do you not eat and why is your heart sad? Am I not better to you than ten sons?”

And she said, Let thine handmaid find grace in thy sight. So the woman went her way, and did eat, and her countenance was no more sad.

It is no longer my pleasure for Saul to be king; for he is turned back from going in my ways, and has not done my orders. And Samuel was very sad, crying to the Lord in prayer all night.
