Matthew 10:2–33
Jesus instructed the twelve as follows:
‘Do not be afraid of them therefore. For everything that is now covered will be uncovered, and everything now hidden will be made clear. What I say to you in the dark, tell in the daylight; what you hear in whispers, proclaim from the housetops. ‘Do not be afraid of those who kill the body but cannot kill the soul; fear him rather who can destroy both body and soul in hell. Can you not buy two sparrows for a penny? And yet not one falls to the ground without your Father knowing. Why, every hair on your head has been counted.  So there is no need to be afraid; you are worth more than hundreds of sparrows.
‘So if anyone declares himself for me in the presence of men, I will declare myself for him in the presence of my Father in heaven. But the one who disowns me in the presence of men, I will disown in the presence of my Father in heaven.
