'Helpless' in the Bible

He waits in ambush near the villages;he kills the innocent in secret places.His eyes are on the lookout for the helpless;

So he is oppressed and beaten down;the helpless fall because of his strength.

But You Yourself have seen trouble and grief,observing it in order to take the matter into Your hands.The helpless entrusts himself to You;You are a helper of the fatherless.

He will have pity on the poor and helplessand save the lives of the poor.

The Lord guards the inexperienced;I was helpless, and He saved me.
