'Stumble' in the Bible

He will then turn his attention to the fortresses of his own land, but he will stumble and fall, not to be found again.

When they stumble, they will be granted some help. But many will unite with them deceitfully.

Even some of the wise will stumble, resulting in their refinement, purification, and cleansing until the time of the end, for it is still for the appointed time.
