So that thou incline thine ear unto wisdom, and apply thine heart to understanding;
[P]atience and sustained effort are required in the acquiring of wisdom. To incline the ear is to listen with attention. To apply the heart is to consider well. He describes the whole process of learning and understanding. The ear must take in and the heart, or mind, must think over what is heard. These verses teach us something about the way the spirit gives us wisdom, while we labor to understand (2 Timothy 2:7). It’s kind of like giving a friend a book. Once you give them the book they own it, but they must read the book to gain the knowledge from it.
