'Ears' in the Bible

And he said, "Whoever has ears to hear had better listen!"

If anyone has ears to hear, he had better listen!"

After Jesus took him aside privately, away from the crowd, he put his fingers in the man's ears, and after spitting, he touched his tongue.

And immediately the man's ears were opened, his tongue loosened, and he spoke plainly.

Though you have eyes, don't you see? And though you have ears, can't you hear? Don't you remember?
