Job 16:21

O that one might plead for a man with God O that either I or some faithful advocate might be admitted to plead my cause, either with God, or rather with you before God's tribunal, God being witness and judge between us. A different translation of this verse is proposed by some, a translation which the Hebrew text will very well bear, namely, And he will plead (that is, there is one that will plead) for man with God, even the Son of man, for his friend or neighbour. Those who pour out tears before God, though they cannot plead for themselves by reason of their distance and defects, have a friend to plead for them, even the Son of man; and on this we must ground all our hopes of acceptance with God.
