'Back' in the Bible

“God will not turn back His anger;Beneath Him crouch the helpers of Rahab.

“If I speak, my pain is not lessened,And if I hold back, what has left me?

“His sons favor the poor,And his hands give back his wealth.

“It is drawn forth and comes out of his back,Even the glittering point from his gall.Terrors come upon him,

He keeps back his soul from the pit,And his life from passing over into Sheol.

To bring back his soul from the pit,That he may be enlightened with the light of life.

“He laughs at fear and is not dismayed;And he does not turn back from the sword.
