Job 39:19

“Hast thou given the horse strength? etc.] Not only to bear burdens and draw carriages, but for war; for it is the war horse that is here spoken of, as what follows shows, and his strength denotes; not strength of body only, but fortitude and courage; for which, as well as the other, the horse is eminent, and both are the gift of God, and not of men; hast thou clothed his neck with thunder? or with strength, as the Targum; the horse having particularly great strength in its neck, as well as in other parts; or with strength of voice, as Ben Gersom explains it; and it has been generally understood of the neighing of horses, which comes through and out of their neck, and makes a vehement sound:…”

“The allusion to "the horse" (Job 39:18), suggests the description of him. Arab poets delight in praising the horse; yet it is not mentioned in the possessions of Job (Job 1:3; Job 42:12). It seems to have been at the time chiefly used for war, rather than "domestic purposes." thunder--poetically for, "he with arched neck inspires fear as thunder does." Translate, "majesty" [UMBREIT]. Rather "the trembling, quivering mane," answering to the "vibrating wing" of the ostrich (see on Job 39:13) [MAURER]. "Mane" in Greek also is from a root meaning "fear." English Version is more sublime.”

“Hast thou given the horse strength? - The incidental allusion to the horse in comparison with the ostrich in the previous verse, seems to have suggested this magnificent description of this noble animal - a description which has never been surpassed or equalled. The horse is an animal so well known, that a particular description of it is here unnecessary. The only thing which is required is an explanation of the phrases used here, and a confirmation of the particular qualities here attributed to the war-horse, for the description here is evidently that of the horse as he appears in war, or as about to plunge into the midst of a battle. The description which comes the nearest to this before…”

“Thunder - A strong metaphor, to denote force and terror. Job 39:21”

“the horse: Exo 15:1; Psa 147:10 clothed: Psa 93:1, Psa 104:1 thunder: Job 39:25; Mar 3:17 Job 39:20”

“19 Dost thou give to the horse strength? Dost thou clothe his neck with flowing hair? 20 Dost thou cause him to leap about like the grasshopper? The noise of his snorting is a terror! 21 He paweth the ground in the plain, and boundeth about with strength. He advanceth to meet an armed host. 22 He laugheth at fear, and is not affrighted, And turneth not back from the sword. 23 The quiver rattleth over him, The glittering lance and spear. 24 With fierceness and rage he swalloweth the ground, And standeth not still, when the trumpet soundeth. 25 He saith at every blast of the trumpet: Ha, ha! And from afar he scenteth the battle, The thundering of the captains and the shout of war. After the…”
