He runneth upon him, even on his neck, upon the thick bosses of his bucklers:
On his neck - rather, 'with outstretched neck'-namely, that of the rebel uplifted hanghtily (Umbreit). (Psalms 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).
