John Gill's Bible Commentary Ver. 4. And by knowledge shalt the chambers be filled with all precious and pleasant riches .] That are both of worth, value, and usefulness, and for ornament and delight; the more private and retired parts of a man’s dwelling house, as well as his shops, warehouses, barns, and granaries, shall be filled with all kind of valuable substance, through his knowledge in improving trade or husbandry, in which he is concerned. This may be understood spiritually, of the fulness which the church has from Christ, and of those unsearchable riches of his she receives from him; and of those treasures of wisdom and knowledge, which the chambers of the soul of a believer are filled with by him; and of all the riches put into them, which are both precious and pleasant; such as precious promises, pleasant doctrines, the valuable truths of the Gospel, and blessings of grace.
Matthew Henry Commentary
Verses 3-6 - Piety and prudence in outward affairs, both go together to complete wise man. By knowledge the soul is filled with the graces and comfort of the spirit, those precious and pleasant riches. The spirit i strengthened for the spiritual work and the spiritual warfare, by tru wisdom.
