'Weak' in the Bible

Thus says the Lord,“Cursed is the man who trusts in and relies on mankind,Making [weak, faulty human] flesh his strength,And whose mind and heart turn away from the Lord.

“A sword against their horses and against their chariotsAnd against all the foreign troops that are in her midst,And they will become [as weak and defenseless as] women!A sword against her treasures, and they will be plundered!

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.
