'Defective' in the Bible

But those who are not his children acted corruptly against him; they are a defective and perverted generation.

They fell away and were as disloyal as their ancestors. They became unreliable, like a defective bow;

They return but not to the Most High. They are like a defective weapon. Their princes will fall by the sword because of their raging tongue, and they will be a laughingstock in the land of Egypt."
