'Servant of the Lord' in the Bible

Who is blind but My servant,or deaf like My messenger I am sending?Who is blind like My dedicated one,or blind like the servant of the Lord?

But this is a people despoiled and plundered;All of them are trapped in holes,Or are hidden away in prisons.They have become a prey with no one to rescue them,And a spoil, with no one to say, “Give them back!”

“No weapon that is formed against you will succeed;And every tongue that rises against you in judgment you will condemn.This [peace, righteousness, security, and triumph over opposition] is the heritage of the servants of the Lord,And this is their vindication from Me,” says the Lord.
