Psalms 19:3

The heavens so declare the glory of God, and proclaim his wisdom, power, and goodness, that all ungodly men are left without excuse. They speak themselves to be works of God's hands; for they must have a Creator who is eternal, infinitely wise, powerful, and good. The counter-changing of day and night is a great proof of the power of God, and calls us to observe, that, as in the kingdom of nature, so in that of providence, he forms the light, and creates the darkness, Is 45:7, and sets the one against the other. The sun in the firmament is an emblem of the Sun of righteousness, the Bridegroom of the church, and the Light of the world, diffusing Divine light and salvation by his gospel to the nations of the earth. He delights to bless his church, which he has espoused to himself; and his course will be unwearied as that of the sun, till the whole earth is filled with his light and salvation. Let us pray for the time when he shall enlighten, cheer, and make fruitful every nation on earth, with the blessed salvation. They have no speech or language, so some read it, and yet their voice is heard. All people may hear these preachers speak in their own tongue the wonderful works of God. Let us give God the glory of all the comfort and benefit we have by the lights of heaven, still looking above and beyond them to the Sun of righteousness.

"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. Sun, moon, and stars are God's traveling preachers; they are apostles upon their journey confirming those who regard the Lord, and judges on circuit condemning those who worship idols.

The margin gives us another rendering, which is more literal, and involves less repetition; "no speech, no words, their voice is not heard;" that is to say, their teaching is not addressed to the ear, and is not uttered in articulate sounds; it is pictorial, and directed to the eye and heart; it touches not the sense by which faith comes, for faith cometh by hearing. Jesus Christ is called the Word, for he is a far more distinct display of Godhead than all the heavens can afford; they are, after all, but dumb instructors; neither star nor sun can arrive at a word, but Jesus is the express image of Jehovah's person, and his name is the Word of God.
