Charles H. Spurgeon on Psalms 119:66

Good judgment and knowledge. No blessings are more suitable than "good judgment and knowledge" "knowledge" of ourselves, of our Saviour, of the way of obedience and "good judgment" to direct and apply this knowledge to some valuable end. These two parts of our intellectual furniture have a most important connexion and dependence upon each other. "Knowledge" is the speculative perception of general truth. "Judgment" is the practical application of it to the heart and conduct. Charles Bridges.
