in a land of darkness;
I did not say to the offspring of Jacob,
bSeek me in vain.’

Isaiah 48:3-6

3 “The former things eI declared of old;
they went out from my mouth, and I announced them;
then suddenly I did them, and they came to pass.
4Because I know that fyou are obstinate,
and your neck is an iron sinew
and your forehead brass,
5 gI declared them to you from of old,
before they came to pass I announced them to you,
lest you should say, h‘My idol did them,
my carved image and my metal image commanded them.’
6 “You have heard; now see all this;
and will you not declare it?
From this time forth iI announce to you new things,
hidden things that you have not known.

John 18:20

20Jesus answered him, I have spoken jopenly kto the world. I have always taught in synagogues and in the temple, where all Jews come together. lI have said nothing in secret.
