Matthew Poole and continuators on Isaiah 42:19

19. Who is blind but my servant ? or deaf as my messenger that I sent? who is blind as he that is prefect , and blind as the LORDS servant .

But no People under Heaven are so blind as the Iews who call themselves my Servants and People, who will not receive their Messiah, though he be recommended to them, with such evident and illustrious Signs, and Miraculous works, as force belief from the most unbelieving, and obstinate Gentiles.

My Messengers, the Singular number being put for the plural, as it is commonly in Scripture.

The Priests and other Teachers whom I appointed to instruct my People in the right way.

As the most eminent Teachers and Rulers of the Iews, whom he calleth Perfect, either because it was their duty to know and teach the way, and truth of God perfectly; or rather Sarcastically, because they pretended to great perfection, and proudly called themselves Rabbies and Masters, as our Saviour observed, and despised the People as cursed and not knowing the Law, Ioh. 7. 49. and dirided Christ, for calling them blind, Ioh. 9. 40.

Marginal references: Chap. 43. [illegible: 1+ letters]; m Which title as it was given to the Iewish People in the first clause of the verse; So here it seems to be given to the Priests, because they were called and obliged to be the Lords Servants, in a special and eminent manner.
