And now I write more of the words of Isaiah,
for my soul delighteth in his words.
For I will liken his words unto my people,
and I will send them forth unto all my children,
for he verily saw my Redeemer,
even as I have seen him.
And my brother, Jacob, also has seen him
as I have seen him;
wherefore, I will send their words forth
unto my children to prove unto them
that my words are true.
Wherefore, by the words of three,
God hath said, I will establish my word.
Nevertheless, God sendeth more witnesses,
and he proveth all his words.
(2 Nephi 11:2-3)
