Significance: Isaiah 28:21 names "Mount Perazim" (הַר־פְּרָצִים, har-Peratzim), directly recalling 2 Samuel 5:20 where David defeated the Philistines at Baal-perazim and declared "the LORD has burst out (פָּרַץ, parats) against my enemies before me like a bursting flood." However, Isaiah shockingly reverses the direction of divine intervention: the LORD will now rise up against His own people in His "strange work" (מַעֲשֵׂהוּ זָר, ma'asehu zar) and "disturbing task." What was once a celebrated victory for Israel (God fighting for David) becomes a template for God fighting against a disobedient Jerusalem. The passage calls judgment on God's own people "alien" precisely because it inverts the expected pattern of divine warfare on Israel's behalf.

Significance: In 2 Samuel 5:20, God "burst out" (פָּרַץ, parats) against David's Philistine enemies at Baal-perazim, giving Israel a stunning victory. Isaiah 28:21 recalls this same event — "the LORD will rise up as at Mount Perazim" — but with a shocking reversal: God's "strange work" (מַעֲשֵׂהוּ זָר, ma'asehu zar) and "alien task" (עֲבֹדָתוֹ נָכְרִיָּה, avodato nokhriyyah) is now directed against Israel itself, not against Israel's enemies. Isaiah's allusion transforms the memory of divine deliverance into a warning of divine judgment, announcing that the same God who fought for Israel at Perazim will now fight against an unrepentant people. This theological reversal represents one of the most powerful uses of historical allusion in prophetic rhetoric.
