Wisdom is found on the lips of the discerning, but a rod is for the back of him who lacks judgment. Perhaps judgement is another word for discernment. The mocker seeks wisdom and finds none, but knowledge comes easily to the discerning. This is a gift. The wise in heart are called discerning, and pleasant words promote instruction.
Discernment is a special kind of wisdom.
It comes from the heart, not the mind. A discerning man keeps wisdom in view, but a fool's eyes wander to the ends of the earth. Discernment keeps wisdom in view - we have to STAY focused on God to have discernment. If we do not, we will lose this gift. Even a fool is thought wise if he keeps silent, and discerning if he holds his tongue.
