on behalf of a man he pleads with God as one pleads for a friend

 Job 15,16

Then Eliphaz the Temanite replied: Would a wise person answer with empty notions or fill their belly with the hot east wind? Would they argue with useless words, with speeches that have no value? But you even undermine piety and hinder devotion to God.

What are mortals, that they could be pure, or those born of woman, that they could be righteous?

All his days the wicked man suffers torment, the ruthless man through all the years stored up for him.

chap 16

Then Job replied: I have heard many things like these; you are miserable comforters, all of you! Will your long-winded speeches never end? What ails you that you keep on arguing? I also could speak like you, if you were in my place; I could make fine speeches against you and shake my head at you. But my mouth would encourage you; comfort from my lips would bring you relief. Yet if I speak, my pain is not relieved; and if I refrain, it does not go away.

yet my hands have been free of violence and my prayer is pure. “Earth, do not cover my blood; may my cry never be laid to rest! Even now my witness is in heaven; my advocate is on high. My intercessor is my friend as my eyes pour out tears to God; on behalf of a man he pleads with God as one pleads for a friend.

Only a few years will pass before I take the path of no return.

Why?

The job was pain and suffering criticized by his friends. 

Yes, all of us have a short life in this world and will pass before I take the path of no return.

We can say nothing about our suffering, someone meets good things, and someone meets troubles. who knows. Our sovereign Lord has his plans. A little life no right to argue with the creator.

How?

Honor the Lord and with humble altitude is our living perspective in this world.
