Matthew 11:14

And if ye will receive it, this is Elias, which was for to come.

If you are willing to receive it, this is Elijah, who is to come.

And if ye are willing to receive `it,' this is Elijah, that is to come.

and if ye are willing to receive `it', he is Elijah who was about to come;

And if you are willing to accept it, he is the Elijah who was to come.
