'Supplication' in the Bible

If thou dost seek early unto God, And unto the Mighty makest supplication,

Whom, though I were righteous, I answer not, For my judgment I make supplication.

To my servant I have called, And he doth not answer, With my mouth I make supplication to him.

Thou dost make supplication unto Him, And He doth hear thee, And thy vows thou completest.

He maketh supplication unto God, And He accepteth him. And he seeth His face with shouting, And He returneth to man His righteousness.
