burning indignation: fierce anger that condemns its object, almost always God's, poured out in judgment.
This word names anger with an edge of condemnation. It comes from a verb that means to denounce or to curse, the word Balaam uses when he protests that he cannot curse the ones God has not cursed. So it is not simply feeling upset; it is anger that speaks, that pronounces a verdict against the one it is aimed at.
In the Hebrew Bible this indignation is nearly always God's. The prophets and psalmists picture it as something poured out, carried like a weapon, filling his lips, marching through the land. It is his settled fury against wrongdoing, discharged in judgment, and the recurring cry is that no one can stand before it.
A handful of passages, especially in Isaiah and Daniel, speak of "the indignation" as a bounded season: a fixed span of divine anger that runs its course and then ceases. And in one human instance, in Hosea, the word turns toward the raging, insolent talk of a people, closer to the root's older sense of cursing.
