'Know' in the Bible

For I want you to know, brothers, that the gospel that was proclaimed by me is not of human origin.

But the churches of the Messiah that are in Judea did not yet know me personally.

yet we know that a person is not justified by doing what the Law requires, but rather by the faithfulness of Jesus the Messiah. We, too, have believed in the Messiah Jesus so that we might be justified by the faithfulness of the Messiah and not by doing what the Law requires, for no human being will be justified by doing what the Law requires.

However, in the past, when you did not know God, you were slaves to things that are not really gods at all.

But now that you know God, or rather have been known by God, how can you turn back again to those powerless and bankrupt basic principles? Why do you want to become their slaves all over again?

You know that it was because I was ill that I brought you the gospel the first time.
