'Helpless' in the Bible

We have heard the report of it;Our hands become limp and helpless.Anguish has gripped us,Pain like that of a woman in childbirth.

“In the shadow of HeshbonThe fugitives stand powerless [helpless and without strength],For a fire has gone out from Heshbon,A flame from the midst of Sihon;It has destroyed the forehead of MoabAnd the crowns of the heads of [the arrogant Moabites] the ones in tumult.

“The king of Babylon has heard the report about them,And his hands fall limp and helpless;Anguish has seized him,And agony like that of a woman in childbirth.

The mighty warriors of Babylon have ceased to fight;They remain in their strongholds.Their strength and power have failed;They are becoming [weak and helpless] like women.Their dwelling places are set on fire;The bars on her gates are broken.
