'Recognize' in the Bible

He was in the world, and the world was created by him, but the world did not recognize him.

John answered them, "I baptize with water. Among you stands one whom you do not recognize,

I did not recognize him, but I came baptizing with water so that he could be revealed to Israel."

And I did not recognize him, but the one who sent me to baptize with water said to me, 'The one on whom you see the Spirit descending and remaining -- this is the one who baptizes with the Holy Spirit.'

When he has brought all his own sheep out, he goes ahead of them, and the sheep follow him because they recognize his voice.

They will never follow a stranger, but will run away from him, because they do not recognize the stranger's voice."
