It is generally understood that this relates to Jesus, however, there are a number of issues, a few mentioned below.
Isaiah 42:
1 - …justice to the nations.
[Jesus did not bring Justice / law – he said that his kingdom is not of this world]
2 -not shout or cry out, or raise his voice in the streets.
[Jesus turn the tables in the temple Matthew 21:12-13]
[Hebrews 5:7: In the days of his flesh, Jesus offered up prayers and supplications, with loud cries and tears,…]
4 -he will not falter or be discouraged till he establishes justice on earth.
[Jesus stated his Kingdom not of this world did not bring justice / law etc…]
6 - a light for the Gentiles,
[Jesus stated he only sent to the lost sheep of Israel]
9 - new things I declare;
[Jesus did not say he came to declare new things – said came not to change a ‘jot’ Matt 5:18]
11 - Kedar lives rejoice. Let the people of Sela sing for joy;
[Kedar is Ishmael son and Sela is a mountain in Medina – not relevant to Jesus or Issac]
13 The LORD will march out like a champion, like a warrior he will stir up his zeal; with a shout he will raise the battle cry and will triumph over his enemies.
[Jesus was never involved in any war and did not triumph over his enemies, quite the opposite]
16 - I will not forsake them.
[Matt 27:46 Eli, Eli, lama sabachthani? that is, My God, my God, why hast thou forsaken me?]
17 But those who trust in idols, who say to images, ‘You are our gods,’
[Jesus was not sent to pagans]
Conclusion:
From the evidence its unlikely that this relates to Jesus
