Jeremiah said:
“I hear the whisperings of many:
‘Terror on every side!
Denounce! let us denounce him!’
All those who were my friends
are on the watch for any misstep of mine.
‘Perhaps he will be trapped; then we can prevail,
and take our vengeance on him.’
But the LORD is with me, like a mighty champion:
my persecutors will stumble, they will not triumph.
In their failure they will be put to utter shame,
to lasting, unforgettable confusion.
O LORD of hosts, you who test the just,
who probe mind and heart,
let me witness the vengeance you take on them,
for to you I have entrusted my cause.
Sing to the LORD,
praise the LORD,
for he has rescued the life of the poor
from the power of the wicked!”

–Jeremiah chapter 20

Jesus said to the Twelve:
“Fear no one.
Nothing is concealed that will not be revealed,
nor secret that will not be known.
What I say to you in the darkness, speak in the light;
what you hear whispered, proclaim on the housetops.
And do not be afraid of those who kill the body but cannot kill the soul;
rather, be afraid of the one who can destroy
both soul and body in Gehenna.
Are not two sparrows sold for a small coin?
Yet not one of them falls to the ground without your Father’s knowledge.
Even all the hairs of your head are counted.
So do not be afraid; you are worth more than many sparrows.
Everyone who acknowledges me before others
I will acknowledge before my heavenly Father.
But whoever denies me before others,
I will deny before my heavenly Father.”

–Gospel of Luke
