'Telling' in the Bible

From now on I am telling you before it comes to pass, so that when it does occur, you may believe that I am He.

Some of His disciples then said to one another, “What is this thing He is telling us, ‘A little while, and you will not see Me; and again a little while, and you will see Me’; and, ‘because I go to the Father’?”

And he who has seen has testified, and his testimony is true; and he knows that he is telling the truth, so that you also may believe.
