'Known' in the Bible

None of the rulers of this age knew this wisdom, for if they had known it, they would not have crucified the Lord of glory.

Forwho has known the Lord’s mind,that he may instruct Him?But we have the mind of Christ.

But if anyone loves God, he is known by Him.

For now we see indistinctly, as in a mirror,but then face to face.Now I know in part,but then I will know fully,as I am fully known.

In the same way, unless you use your tongue for intelligible speech, how will what is spoken be known? For you will be speaking into the air.
