'Helper' in the Bible

You have seen it, for You have beheld mischief and vexation to take it into Your hand.The unfortunate commits himself to You;You have been the helper of the orphan.

“Hear, O Lord, and be gracious to me;O Lord, be my helper.”

Behold, God is my helper;The Lord is the sustainer of my soul.

For he will deliver the needy when he cries for help,The afflicted also, and him who has no helper.
