'Profited' in the Bible

What is the Almighty that we should serve him? and what are we profited if we pray unto him?

He looketh upon men, and if any say, I have sinned, and perverted that which was right, and it profited me not;

“For you say, ‘What advantage have you [by living a righteous life]?What profit will I have, more [by being righteous] than if I had sinned?’

You sell Your people cheaply,And have not profited by their sale.

What is a man profited by all his work which he does under the sun?

There are words without number for increasing what is to no purpose, but what is man profited by them?
