The projecting center of a shield. Job 15:26; "he (the rebel) runneth upon Him (God), even on (rather with) his neck (i.e. the rebel's haughtily uplifted neck, Psalm 75:5); upon (rather with) the thick bosses of his (the rebel's, not God's) bucklers." The rebel and his fellows, as it were, join shield to shield as a compact covering against the Almighty's darts. What suicidal folly! for "the shields of the earth belong unto God" (Psalm 47:9). The invading godless Gog and Magog's shields Israel shall "set on fire" (Ezekiel 39:9).
