'Helpless' in the Bible

So your poverty will come like an approaching prowler who walks [slowly, but surely]And your need [will come] like an armed man [making you helpless].

Don't rob the poor person because he is poor, and don't crush the helpless in court,

A poor man who oppresseth the helpless is a sweeping rain which leaveth no food.

A wicked ruler over a helpless peopleis like a roaring lion or a charging bear.
