Job 39:24

Raging and snorting he swalloweth the earth, neither believeth he that the blast of the trumpet soundeth. 66. For it was said to the first man when he sinned; Earth thou art, and to earth shalt thou go. [Gen. 3, 19] But the trumpets sound, when the powers of this world awfully prohibit holy men from preaching. Because, therefore, a preacher, inflamed by the zeal of the Holy Spirit, ceases not, even when set in the midst of punishments, to attract any sinners whomsoever to himself, he doubtless in his rage swalloweth the earth, but because he fears not at all the threats of persecutors, he believeth not that the blast of the trumpet soundeth. For what else is the 'trumpet,' which announces the peril of the contest, but the voice of worldly powers, which prepares when contemned the contest of death for those who resist? 67. This trumpet had been sounded by the chief priests, when they commanded the Apostles, when scourged, not to speak of God; as it is written; They commanded them, when they had been scourged, that they should not preach in the name of Jesus. [Acts 5, 40] But let us see how the blast of the trumpet frightens not the horse of God. Peter says; We ought to obey God, rather than men. [ib. 29] Who says also to others who were persecuting him; For we cannot but speak the things which we have seen and heard. [Acts 4, 20] The horse of God, therefore, fears not the blast of the trumpet, because the illustrious preacher, having despised the powers of the world, fears not the sounds of any threats. 68. Let us see how another horse of God swalloweth the earth, and how no dread of the trumpet reaches him. For it is written; There came down certain Jews from Antioch and Iconium, and, having persuaded the multitude, they stoned Paul, and drew him out of the city, supposing he had been dead. […]

But the horse is still not struck with terror by this sound, and so he says, "raging," from interior courage, "and snorting," that is, neighing. He calls this a roar which is the sound characteristic of lions (Proverbs 19:12) because of the courage of the …

Raging and snorting, he swalloweth the earth, neither believeth he that the blast of the trumpet soundeth. [MORAL INTERPRETATION] 83. The blast of the trumpet sounds against the horse, when any sin, placed nigh, fearfully assails the mind of an Elect one, in that which he does boldly. But raging and snorting he swalloweth the earth, because he rouses himself by his violent ardour; and consumes, by daily advancing, whatever earthly things he finds within him.

Swalloweth - He is so full of rage and fury, that he not only champs his bridle, but is ready to tear and devour the very ground on which he goes. Believeth - He is so pleased with the approach of the battle, and the sound of the trumpet calling to it, that he can scarce believe his ears for gladness.

He swalloweth the ground with fierceness and rage,.... Being so eager for the battle, and so full of fierceness and rage, he bounds the plain with such swiftness that he seems rather to swallow up the ground than to run upon it; neither believeth he that it is the sound of the trumpet; for joy at hearing it; or he will not trust to his ears, but will see with his eyes whether the battle is ready, and therefore pushes forward.
