For the Hebrew people that shining of the face of God became spiritual and potent for salvation less through the law, the priesthood, and the ritual, than through psalm and prophecy. Of the revelation of the law Paul says, "The ministration of death written and engraven on stones came with glory, so that the children of Israel could not look steadfastly upon the face of Moses, for the glory of his face." With such holy and awful brightness did God appear in the law, that Moses had to cover his face from which the splendour was reflected. But the psalmist, pressing towards the light with fine spiritual boldness and humility, could say, "When Thou saidst, Seek ye My face; my heart said unto Thee, Thy face, Lord, will I seek" (Psalm xxvii. 8); and again, "Turn us again, O God of hosts, and cause Thy face to shine; and we shall be saved" (Psalm lxxx. 7). And in an oracle of Isaiah (liv. 8), Jehovah says, "In overflowing wrath I hid My face from thee for a moment; but with everlasting kindness shall I have mercy on thee."
In the third clause of the benediction the peace of God, that calm of mind, conscience, and life which accompanies salvation, is invoked. From the trouble and sorrow and tumult of existence, from the fear of hostile power, from evil influences seen and unseen, the Divine hand will give salvation. It seems indeed to be the meaning that the gracious regard of God is enough. Are His people in affliction and anxiety? Jehovah's look will deliver them. They will feel calmly safe as if a shield were interposed between them and the keen arrows of jealousy and hatred. "In covert of Thy presence shalt Thou hide them from the plottings of man: Thou shalt keep them secretly in a pavilion from the strife of tongues." Their tranquillity is described by Isaiah: "In righteousness shalt thou be established: thou shalt be far from oppression, for thou shalt not fear; and from terror, for it shall not come near thee ... no weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn. This is the heritage of the servants of the Lord, and their righteousness which is of Me, saith the Lord."
The peace of the human soul is not, however, entirely provided for by the assurance of Divine protection from hostile force. A man is not in perfect tranquillity because he belongs to a nation or a church defended by omnipotence. His own troubles and fears are the main causes of unrest. And the Spirit of God, who cleanses and renews the soul, is the true Peace-giver. "To win true peace a man needs to feel himself directed, pardoned, and sustained by a supreme power, to feel himself in the right road, at the point where God would have him to be--in order with God and the universe." In his heart the note of harmony must be struck deep and true, in profound reconciliation and unity with God. With this in view the oracles of Ezekiel connect renewal and peace. "I will put My Spirit in you, and ye shall live ... I will make a covenant of peace with them; it shall be an everlasting covenant with them ... and I will set My sanctuary in the midst of them for evermore."
The protection of God the Father, the grace and truth of the Son, the comfort and peace of the Spirit--were these, then, implied in Israel's religion and included in this blessing of Aaron? Germinally, at least, they were. The strain of unity running through the Old and New Testaments is heard here and in the innumerable passages that may be grouped along with the threefold benediction. The work of Christ, as Revealer and Saviour, did not begin when He appeared in the flesh. As the Divine Word He spoke by every prophet and through the priest to the silent congregations age after age. Nor did the dispensation of the Spirit arise on the world like a new light on that day of Pentecost when the disciples of Christ were gathered in their upper chamber and the tongues of fire were seen. There were those even in the old Hebrew days on whom the Spirit was poured from on high, with whom "judgment dwelt in the wilderness, and righteousness in the fruitful field: and the work of righteousness was peace, and the effect of righteousness quietness and assurance for ever." He who is our peace came in the appointed time to fill with eternal meaning the old benedictions, and set our assurance on the immovable rock of His own sacrifice and power.
