'Saviour' in the Bible

for in a field he found her, she hath cried -- the damsel who is betrothed -- and she hath no saviour.

and thou hast been gropling at noon, as the blind gropeth in darkness; and thou dost not cause thy ways to prosper; and thou hast been only oppressed and plundered all the days, and there is no saviour.

thine ox is slaughtered before thine eyes, and thou dost not eat of it; thine ass is taken violently away from before thee, and it is not given back to thee; thy sheep are given to thine enemies, and there is no saviour for thee.
