Job 15:26

“He runneth upon him, [even] on [his] neck, etc.] As a fierce and furious enemy runs upon another with great wrath and fury; as the he goat in Daniel’s vision ran upon the ram, in the fury of his power, that is, Alexander upon Darius; which instance Bar Tzemach refers to; and as an adversary, who throws down his weapons, and goes in to closer quarters, and takes his antagonist by the throat, or round the neck, in order to throw him down to the ground; in such a bold and insolent manner does the wicked man encounter with God; he makes up to him, and flies in his face, and most audaciously attacks him: or he runs upon him “with [his] neck” f629 ; with a stretched out neck, in the most haughty…”

“on his neck--rather, "with outstretched neck," namely, that of the rebel [UMBREIT] (Psa 75:5). upon . . . bucklers--rather, "with--his (the rebel's, not God's) bucklers." The rebel and his fellows are depicted as joining shields together, to form a compact covering over their heads against the weapons hurled on them from a fortress [UMBREIT and GESENIUS].”

“He runneth upon him - That is, upon God. The image here is taken from the mode in which people rushed into battle. It was with a violent concussion, and usually with a shout, that they might intimidate their foes, and overcome them at first, with the violence of the shock. The mode of warfare is now changed, and it is the vaunted excellency of modern warfare that armies now go deliberately and calmly to put each other to death. Even “on his neck - literally, “with the neck” - בצואר betsavā'r. Vulgate, “With erect neck - erecto collo.” Septuagint, contemptuously, or with pride - ὕβρει hubrei. The idea seems to be, not that he ran “upon the neck” of his adversary - as would seem to be…”

“He - The wicked man. Neck - As a stout warrior who cometh close to his adversary and grapples with him. He acts in flat opposition to God, both to his precepts and providences. Bosses - Even where his enemy is strongest. Job 15:27”

“runneth: Ch2 28:22, Ch2 32:13-17 even on: Job 16:12; Gen 49:8; Psa 18:40 Job 15:27”
