Both the heart and the ear of the wise are active — getting and seeking knowledge. This is not passive receiving but active pursuit. The heart here is the seat of understanding; the ear is the instrument of receiving instruction. Wisdom does not coast on what it already knows — it keeps reaching for more.
Memory phrase: Wise hearts keep learning.
Talk about it: How do wise people keep growing in what they know?
Prayer: God, give me a heart and ears eager to learn.
