The wise person always wants to learn more. That person listens closely for more wisdom.
The heart of the prudent getteth knowledge; And the ear of the wise seeketh knowledge.
The mind of the prudent is ever getting knowledge, and the ear of the wise is ever seeking (inquiring for and craving) knowledge.
An understanding mind gains knowledge; the ear of the wise seeks knowledge.
A prudent heart shall possess knowledge. And the ear of the wise seeks doctrine.
A wise heart shall acquire knowledge: and the ear of the wise seeketh instruction.
