The list maker has taken a verse about the prophet Isaiah and claimed it is a prophecy about Jesus.
How can we be sure that it is Isaiah and not Jesus?
"The L-rd G-d gave me a tongue for teaching (לִמּוּדִ֔ים -- not counselor), to know to establish times for the faint [for His] word; He awakens me every morning, He awakens My ear, to hear according to the teachings." Y'shayahu / Isaiah 50:4
The pronoun is first person.
The person who is teaching is the speaker.
Who is the speaker?
Isaiah, the prophet.
This is not rocket science.
Isaiah describes himself in this passage -- he remarks on his good faith and willingness to subject himself to humiliation in his prophetic career. "The L-rd G-d opened my ear, and I did not rebel; I did not turn away backwards. I gave my back to smiters and my cheeks to them that plucked off the hair; I did not hide my face from embarrassments and spitting. But the L-rd G-d helps me, therefore, I was not embarrassed; therefore, I made my face like flint, and I knew that I would not be ashamed." Y'shayahu / Isaiah 50:5 - 7.
The Jewish sages Rashi Ibn Ezra and Kimchi (the Radak) all reached this conclusion. The Radak wrote "This is what the prophet said about himself."
Y'shayahu / Isaiah 50:4 - 9 is the third of Isaiah's four Servant Songs.
Although the Hebrew word for "servant" does not explicitly appear in Y'shayahu / Isaiah 50:4-9 the descriptions of the servant's characteristics are quite similar to those of the servant found in the other three Servant Songs. None have any allusion to the Jesus unless the context (and even the pronouns!) are ignored.
The list maker references Matthew 11:28 and 29 as "proof" but neither passage mentions Jesus as a teacher (not counselor). Matthew speaks of Jesus giving rest to the weary -- not teaching them. Even if Jesus did teach, was a counselor and helped the weary "so what"? There are tens of thousands (if not millions) of teachers alive today -- simply being a teacher is not "proof" that Y'shayahu / Isaiah 50:4 is about Jesus. Yet again the list maker makes a claim that does not fit Jesus.
Many Christian commentators admit the passage in Isaiah is about the prophet "This and the following passages may be in some sort understood of the prophet Isaiah," (Matthew Henry), and "This and the following passages may be, in some sort, understood of the Prophet Isaiah" Benson Commentary even as the Christians go on to insist that even so it is really about Jesus.
