_"Whatsoever things were written aforetime were written for our
learning, that we through patience and comfort of the Scriptures might
have hope." Rom. xv. 4._

_"My people shall know my name, therefore they shall know in that day
that I am he that doth speak, Behold, it is I." Isaiah lii. 6._

In the New Testament we have in the Gospels and the Epistles God's
teachings concerning the Old Testament. The writers of the New Testament
had the promise of our Lord that "The Comforter, who is the Holy Spirit,
whom the Father will send in my name, He shall teach you all things, and
bring all things to your remembrance, whatsoever I have said unto you."
(John xiv. 26.)

In the fulfillment of this promise they have given us the testimony of
God, the Holy Spirit, on all the subjects of which they have written.
What, therefore, is their testimony concerning the author of the book of
Isaiah? Did that prophet write the book, or is it a patched book from
various authors?

Matthew, the inspired author of the book that bears his name, quotes
from Isaiah xl. 3: "The voice of him that crieth in the wilderness,
Prepare ye the way of the Lord, make straight in the desert a highway
for our God." (See Matt. iii. 3.)

The critics inform us that this prophecy was not given by Isaiah, but by
some unknown prophet, and was bound up with Isaiah's prophecies, and
labeled as his. Matthew informs us that it was a prophecy concerning
John the Baptist, and was given by Isaiah himself, and not by another.
He says (iii. 3), referring to John the Baptist: "For this is he that
was spoken of through _Isaiah the prophet_, saying:

"The voice of one crying in the wilderness, Make ye ready the way of the
Lord, Make his paths straight." (R.V.)

Again, in Matt. viii. 17, the author of this gospel quotes a passage
from the fifty-third chapter of Isaiah. The critics have handed this
fifty-third chapter over to the Unknown prophet or prophets. They affirm
again that the theme and literary style of this chapter are such that
Isaiah could not have written it. They base their affirmation on their
own literary discoveries, their ability to detect the footprints of some
other prophet, though they do not inform us who that prophet is. The
