John 4:51-53

And as he was now going down, his servants met him, and told him, saying, Thy son liveth.

Then enquired he of them the hour when he began to amend. And they said unto him, Yesterday at the seventh hour the fever left him.

So the father knew that it was at the same hour, in the which Jesus said unto him, Thy son liveth: and himself believed, and his whole house.
