Isaiah 42:20 in the World English Bible
You see many things, but don’t observe. His ears are open, but he doesn’t listen.
Context
19 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?
20 Seeing many things, but thou observest not; opening the ears, but he heareth not.
21 The LORD is well pleased for his righteousness’ sake; he will magnify the law, and make it honourable.
