There is no speech nor language; Their voice is not heard.
"There is no speech nor language, where their voice is not heard." Every man may hear the voices of the stars. Many are the languages of terrestrials, to celestials there is but one, and that one may be understood by every willing mind. The lowest heathen are without excuse, if they do not discover the invisible things of God in the works which he has made.
David sets before us two mirrors of God's glory: first the heavens themselves with their exquisite order, then the Law in which God made Himself known to His chosen people. From this he moves to praise the Law at length before closing with prayer.
