Whoever gets sense loves his own soul; he who keeps understanding will discover good.

Those are here encouraged, 1. That take pains to get wisdom, to get knowledge, and grace, and acquaintance with God; those that do so show that they love their own souls, and will be found to have done themselves the greatest kindness imaginable.

He that getteth wisdom loveth his own soul,.... Wisdom and knowledge in things natural and civil; and especially in things divine, spiritual, and evangelical; particularly he that gets Christ, the Wisdom of God, and a saving knowledge of him; see Pro 3:13.
