'Comforts' in the Bible

I directed their course and presided as chief.I lived as a king among his troops,like one who comforts those who mourn. >

I—I am the One who comforts you.Who are you that you should fear man who dies,or a son of man who is given up like grass?

As a mother comforts her son,so I will comfort you,and you will be comforted in Jerusalem.
