Let the LORD, the God of the {d} spirits of all flesh, set a man over the congregation,

(d) Who as he has created, so he governs the hearts of all men.

Wesley's Notes

27:16 The Lord of the spirits of all flesh - God of all men: the searcher of spirits, that knowest who is fit for this great employment; the father and giver and governor of spirits, who canst raise and suit the spirits of men to the highest and hardest works.

Jamieson-Fausset-Brown Bible Commentary

16. God of the spirits of all flesh, set a man over the congregation-The request was most suitably made to God in this character, as the Author of all the intellectual gifts and moral graces with which men are endowed, and who can raise up qualified persons for the most arduous duties and the most difficult situations.

Matthew Henry's Concise Commentary

27:15-23 Envious spirits do not love their successors; but Moses was not one of these. We should concern ourselves, both in our prayers and in our endeavours, for the rising generation, that religion may be maintained and advanced, when we are in our graves. God appoints a successor, even Joshua; who had signalized himself by his courage in fighting Amalek, his humility in ministering to Moses, and his faith and sincerity in witnessing against the report of the evil spies. This man God appoints to succeed Moses; a man in whom is the Spirit, the Spirit of grace. He is a good man, fearing God and hating covetousness, and acting from principle. He has the spirit of government; he is fit to do the work and discharge the trusts of his place. He has a spirit of conduct and courage; he had also the Spirit of prophecy. That man is not fully qualified for any service in the church of Christ, who is destitute of the graces and gifts of the Holy Spirit, whatever human abilities he may possess. And in Joshua's succession we are reminded that the law was given by Moses, who by reason of our transgression could not bring us to heaven; but grace and truth came by Jesus Christ, for the salvation of every believer.
