'Blessed is the people that know the joyful sound: they shall walk, O Lord, in the light of Thy countenance.'--PSALM lxxxix. 15.
The Psalmist has just been setting forth, in sublime language, the glories of the divine character--God's strength, His universal sway, the justice and judgment which are the foundation of His Throne, the mercy and truth which go as heralds before His face. A heathen singing of any of his gods would have gone on to describe the form and features of the god or goddess who came behind the heralds, but the Psalmist remembers 'Thou shalt not make unto thyself any ... likeness of God.' A sacred reverence checks his song. He veils his face in his mantle while He whom no man can see and live passes by. Then he breaks into rapturous exclamations which are very prosaically and poorly represented by our version. For the text is not a mere statement, as it is made to be by reading 'Blessed is the people,' but it is a burst of adoring wonder, and should be read, 'Oh! the blessedness of the people that know the joyful sound.'
Now, the force of this exclamation is increased if we observe that the word that is rendered 'joyful sound' is the technical word for the trumpet blast at Jewish feasts. The purpose of these blasts, like those of the heralds at the coronation of a king, was to proclaim the presence of God, the King of Israel, in the festival, as well as to express the gladness of the worshippers. Thus the Psalmist, when he says, 'Blessed is the people that know the joyful sound,' has no reference, as we ordinarily take him to have, to the preaching of the Gospel, but to the trumpet-blasts that proclaimed the present God and throbbed with the gladness of the waiting worshippers. So that this exclamation is equivalent to 'Oh! how blessed are the people who are sure that they have God with them!' and who, being sure, bow before Him in loving worship. It is to be further noticed that the subsequent words of the text state the first element which it indicates of that blessedness of a devout life, 'They shall walk, O Lord! in the light of Thy countenance.'
I. We deal first with the meaning of this phrase.
Of course, 'the light of Thy countenance' is a very obvious and natural symbol for favour, complacency, goodwill on the part of Him that is conceived of as looking on any one. We read, for instance, in reference to a much lower subject in the Book of Proverbs, 'In the light of the king's countenance is life, and his favour is as a cloud of the latter rain.' Again we have, in the Levitical benediction, the phrase accompanied in the parallel clauses by what is really an explanation of it, 'The Lord cause His face to shine upon thee and be gracious unto thee.' So that the simple and obvious meaning of the words, 'the light of Thy countenance,' is the favour and lovingkindness of God manifested in that gracious Face which He turns to His servants. As for the other chief word in the clause, 'to walk' is the equivalent throughout Scripture for the conduct of the active life and daily conversation of a man, and to walk in the light is simply to have the consciousness of the divine Presence and the experience of the divine lovingkindness and friendship as a road on which we travel our life's journey, or an atmosphere round us in which all our activities are done and in which we ever remain, as a diver in his bell, to keep evil and sin from us.
There is only one more remark in the nature of explanation which I make, and that is that the expression here for walking is cast in the original into a form which grammarians call intensive, strengthening the simple idea expressed by the word. We may express its force if we read, 'They walk continually in the light of Thy countenance.'
