'Ears' in the Bible

Whoso stoppeth his ears at the cry of the poor, he also shall cry himself, but shall not be heard.

Speak not in the ears of a fool: for he will despise the wisdom of thy words.

Apply thine heart unto instruction, and thine ears to the words of knowledge.

He that passeth by, and meddleth with strife belonging not to him, is like one that taketh a dog by the ears.
