'Confirmed' in the Bible

But if he doesn't listen, take one or two others with you so that "every word may be confirmed by the testimony of two or three witnesses.'

while our testimony about the Messiah has been confirmed among you.

how will we escape if we neglect a salvation as great as this? It was first proclaimed by the Lord himself, and then it was confirmed to us by those who heard him,

Therefore we regard the message of the prophets as confirmed beyond doubt, and you will do well to pay attention to it, as to a lamp that is shining in a gloomy place, until the day dawns and the morning star rises in your hearts.
