'Enough' in the Bible

I answered, "Oh, Lord God, I really do not know how to speak well enough for that, for I am too young."

I said, "Who is wise enough to understand why this has happened? Who has a word from the Lord that can explain it? Why does the land lie in ruins? Why is it as scorched as a desert through which no one travels?"

The Lord cried out, "Who in the world will have pity on you, Jerusalem? Who will grieve over you? Who will stop long enough to inquire about how you are doing?
