Hear thou, my son, and be wise, and guide thine heart in the way.
– Proverbs 23:19
Verses 19-21 warn against excess. The saying begins with the exhortation to hear, which the word means to listen with intelligence. This common exhortation in Proverbs emphasizes the necessity of deliberate listening and paying attention to the instructions of wisdom in order to be wise (Proverbs 4:10-23). Proverbs teaches true wisdom is alien to us and must be acquired. Wisdom requires keeping our heart, or mind, straight in the way of wisdom.
