'Helper' in the Bible

Thou hast seen it; for thou beholdest mischief and spite, to requite it with thy hand: the poor committeth himself unto thee; thou art the helper of the fatherless.

Hear, O LORD, and have mercy upon me: LORD, be thou my helper.

Behold, God is mine helper: the Lord is with them that uphold my soul.

For he shall deliver the needy when he crieth; the poor also, and him that hath no helper.
