'Grieving' in the Bible

Then Elkanah her husband said to her, “Hannah, why do you cry and why do you not eat? Why are you so sad and discontent? Am I not better to you than ten sons?”

I behaved as if grieving for my friend or my brother;I bowed down in mourning, as one who sorrows for his mother.

‘Why have we fasted,’ they say, ‘and You do not see it?Why have we humbled ourselves and You do not notice?’Hear this [O Israel], on the day of your fast [when you should be grieving for your sins] you find something you desire [to do],And you force your hired servants to work [instead of stopping all work, as the law teaches].
