'Defenseless' in the Bible

Open your mouth for the mute,For the rights of all who are unfortunate and defenseless;

“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!

Thus says the Lord,“For three transgressions of Gaza [in Philistia] and for four (multiplied delinquencies)I will not reverse its punishment or revoke My word concerning it,Because [as slave traders] they took captive the entire [Jewish] population [of defenseless Judean border villages, of which none was spared]And deported them to Edom [for the slave trade].

Why do You make men like the fish of the sea,Like reptiles and creeping things that have no ruler [and are helpless against their enemies]?

And not a creature exists that is concealed from His sight, but all things are open and exposed, and revealed to the eyes of Him with whom we have to give account.
