27:21 And he shall stand before Eleazar the priest, who shall ask [counsel] for him after the {h} judgment of Urim before the LORD: at his word shall they go out, and at his word they shall come in, [both] he, and all the children of Israel with him, even all the congregation.
(h) According to his office: signifying that the civil magistrate could execute nothing but that which he knew to be the will of God.
27:21 Who shall ask counsel for him - When he requires him to do so, and in important and difficult matters. Of Urim - Urim is put for both Urim and Thummim. Before the Lord - Ordinarily in the tabernacle near the second veil setting his face to the ark. At his word - The word of the Lord, delivered to him by the high priest.
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.
