From the transcript....

My sheep know my voice. Is that what he said?

Yeah. My sheep hear my voice. He said both of them. Hear my voice. I think he did say know though.

Because he went on to say, let's get into the technicality of words. All the words before me were things of policy. Yeah, here I am. Let me see what the New King James says. Let me bring up the real Bible. Let me see what the New King James says.

Well, he said, be my memories. The sheep hear his voice. He calls his own sheep by name, leads them out. He knows them, for they know his voice. And they know. He calls my name because he knows them. They know his voice. Yeah.

So there wasn't any conditionality in any of those statements. It's just a fact.
