'Able' in the Bible

So give your servant a discerning mind so he can make judicial decisions for your people and distinguish right from wrong. Otherwise no one is able to make judicial decisions for this great nation of yours."

But when I leave you, the Lord's spirit will carry you away so I can't find you. If I go tell Ahab I've seen you, he won't be able to find you and he will kill me. That would not be fair, because your servant has been a loyal follower of the Lord from my youth.

The Lord's angelic messenger came back again, touched him, and said, "Get up and eat, for otherwise you won't be able to make the journey."
