'Knowledge' in the Bible

You [Samaritans] do not know what you worship; we [Jews] do know what we worship, for salvation is from the Jews.

I am no longer in the world; yet they are still in the world, and I am coming to You. Holy Father, keep them in Your name, the name which You have given Me, so that they may be one just as We are.

While I was with them, I was keeping them in Your name which You have given Me; and I guarded them and protected them, and not one of them was lost except the son of destruction, so that the Scripture would be fulfilled.
