“My sheep listen to my voice, and I know them …”
“I know them.”
It’s funny … wouldn’t you expect the Lord to have said, “My sheep listen to my voice and they know me”?
That would be parallelism. That would be equivalent. That would speak of our recognition of the Good Shepherd, just as the first part of the verse emphasizes it. We know his voice, and we know him.
But it’s not that.
