Hear, ye deaf; and look, ye blind, that ye may see. Who is blind, but my servant? or deaf, as my messenger that I sent? who is blind as he that is perfect, and blind as the LORD’S servant? Seeing many things, but thou observest not; opening the ears, but he heareth not. The LORD is well pleased for his righteousness’ sake; he will magnify the law, and make it honourable. But this is a people robbed and spoiled; they are all of them snared in holes, and they are hid in prison houses: they are for a prey, and none delivereth; for a spoil, and none saith, Restore.
In verse 19 the servant is no longer the Messiah. It is Israel, deaf and blind to the words and works of Jehovah. Israel was brought into covenant relationship with the Lord, but did not walk worthy of her high calling. The Lord exalted the law, as it was honorable to Him, but Israel despised and disobeyed it, and as a result was given over to robbery, plunder, and prison.
