Job 37:4

After it a voice roareth: he thundereth with the voice of his excellency; and he will not stay them when his voice is heard.

After it a voice roareth,.... After the lightning comes a violent crack or clap of thunder, which is like the roaring of a lion. Such is the order of thunder and lightning, according to our sense and apprehension of them; otherwise in nature they are together: but the reasons given why the lightning is seen before, and so the same in the flash and report of a gun, are, because the sense of seeing is quicker than the sense of hearing {y}; and the motion of light is quicker than that of sound; which latter is the truest reason {z}. The roaring voice of thunder may be an emblem of the thunder of the law; its dreadful volleys of curses, vengeance, and wrath on the breakers of it, as delivered out by Boanergeses, sons of thunder, Mark 3:17: or the loud proclamation of the Gospel, made by the ministers of it; and the alarming awakening sound of the word, when attended with the Spirit and power of God, to sinners asleep and dead in trespasses and sins; upon which they awake, hear, and live;

he thundereth with the voice of his excellency: that is, God thunders with such a voice, an excellent and majestic one; for his voice of thunder is full of majesty, Psalms 29:4. So is the voice of Christ in the Gospel; he spake when on earth as one having authority, and he comes forth and appears in it now with majesty and glory; and speaks in it of the excellent things which he has done, of the excellent righteousness he has wrought out, of the excellent sacrifice he has offered up, and of the excellent salvation he is the author of;

and he will not stay them when his voice is heard; either the thunder and the lightning, as some; which he does not long defer after he has given out the decree concerning them, the order and disposition for them: or rather the rain and hail; these are not stayed, but quickly follow the flash of lightning and clap of thunder: "for when he utters his voice of thunder, there is a multitude of waters in the heavens"; and these quickly come down and are not stopped, Jeremiah 10:13. The word for "stay" signifies "to supplant", or "act deceitfully"; the name of Jacob is derived from this root, because he supplanted his brother,

Genesis 25:26; and so it may be rendered here, "he will not supplant", or "deceive them {a}, when his voice is heard": that is, either he does not subvert them, the heavens and earth, but preserves them; though he makes them to tremble with his voice of thunder {b}: or he does not act the part of a secret, subtle, and deceitful enemy, when he thunders; but shows himself openly as a King, executing his decrees with authority {c}: or rather he deceives none with his voice; none can mistake it; all know it to be the voice of thunder when it is heard: so Christ's sheep know his voice in the Gospel, and cannot be deceived; the voice of a stranger they will not follow, John 10:4.

{z} The noise is commonly about seven or eight seconds after the flash, that is, about half a quarter of a minute; but sometimes much sooner, in a second or two, or less than so, and almost immediately upon the flash: this is when the explosion is very near us.
