'Someone' in the Bible

The sick man answered him, "Sir, I have no one to put me into the pool when the water is stirred up. While I am trying to get into the water, someone else goes down there before me."

I have come in my Father's name, and you do not accept me. If someone else comes in his own name, you will accept him.

Never before has anyone heard of someone causing a man born blind to see.

Others said, "These are not the words of someone possessed by a demon. A demon cannot cause the blind to see, can it?"
