'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.

But to the rest of you in Thyatira, who do not hold this teaching, who have not explored and known the depths of Satan, as they call them—I place no other burden on you,

Those whom I [dearly and tenderly] love, I rebuke and discipline [showing them their faults and instructing them]; so be enthusiastic and repent [change your inner self—your old way of thinking, your sinful behavior—seek God’s will].

Then I saw another angel flying in midheaven, with an eternal gospel to preach to the inhabitants of the earth, to every nation and tribe and language and people;

And the angel said unto me, Wherefore didst thou marvel? I will tell thee the mystery of the woman, and of the beast that carrieth her, which hath the seven heads and ten horns.
