'Comfort' in the Bible

Now when Job's three friends heard of all this evil that had come on him, they each came from his own place: Eliphaz the Temanite, Bildad the Shuhite, and Zophar the Naamathite, and they made an appointment together to come to sympathize with him and to comfort him.

When I say, 'My bed shall comfort me. My couch shall ease my complaint;'

Aren't my days few? Cease then. Leave me alone, that I may find a little comfort,

So how can you comfort me with nonsense, because in your answers there remains only falsehood?"
