'Tell' in the Bible

Dismiss your fears concerning all that you are about to suffer. I tell you that the Devil is about to throw some of you into prison that you may be put to the test, and for ten days you will have to endure persecution. Be faithful to the End, even if you have to die, and then I will give you the victor's Wreath of Life.

I tell you that I am about to cast her upon a bed of sickness, and I will severely afflict those who commit adultery with her, unless they repent of conduct such as hers.

And I saw another angel flying across the sky, carrying the Good News of the Ages to tell to every nation, tribe, language and people, among those who live on the earth.
