1 Nephi 20:6–8

Thou hast seen and heard all this;
and will ye not declare them?

And that I have showed thee new things from this time,
even hidden things,
and thou didst not know them.

They are created now, and not from the beginning,
even before the day when thou heardest them not
they were declared unto thee,
lest thou shouldst say—”Behold I knew them.”

Yea, and thou heardest not;
yea, thou knewest not;

Yea, from that time thine ear was not opened;
for I knew that thou wouldst deal very treacherously,
and wast called a transgressor from the womb.
