a striking blow: the impact that brings something down, whether a deadly stroke against a people or a foot hitting a stone
This word is the noun of a verb that means to hit something hard enough to damage it (נָגַף). It names the blow itself, the instant of impact, and not the disease that a blow might amount to or the thing that delivers it. Hebrew has a fuller word for the resulting disaster (מַגֵּפָה), measured by the dead it leaves behind; this one stays with the moment of the strike. That is why one short word can cover both the death of Egypt's firstborn in a single night and a rock that catches a walker's foot.
Six of its seven appearances name a deadly stroke falling on a people, and most of them share a striking feature: the blow is spoken of as something that can be held off.
- The blood on the doorposts keeps it away from Israel's houses on Passover night.
- A ransom paid at the census keeps it from breaking out when the people are counted.
- The Levites serving at the tent of meeting keep it away from the rest of Israel.
- Aaron running into the crowd with incense stops it once it has already started.
When it does land, after Korah's rebellion and after the sin at Peor, the text says only that it had begun, and someone has to get between it and the people.
The seventh appearance turns the picture inside out. Isaiah says God will be a place of safety and, at the very same time, a stone that the two houses of Israel strike their feet against, set next to a rock they trip over (מִכְשׁוֹל). The image stays deliberately physical, a foot meeting a rock in the road, and it works because of that: the same God is shelter to one person and the thing that brings down another, depending on how they come to him. The New Testament reaches back to this line for its own picture of a stone people stumble over.
Nuances
How much of the weight in Isaiah 8:14's "stone of striking" falls on the concrete image of a struck foot and how much on divine judgment.
- majorityThe phrase retains its concrete kinetic force, a literal road-hazard rock, and functions as a figure precisely because it does: Yahweh himself becomes what Israel walks into, sanctuary to some and downfall to others.; H. Wildberger, Isaiah 1-12: A Commentary, trans. T.H. Trapp (Continental Commentary, Fortress, 1991), on 8:14; H.G.M. Williamson, Isaiah 6-12 (ICC, T&T Clark, 2018), on 8:14; J. Blenkinsopp, Isaiah 1-39 (Anchor Bible, Doubleday, 2000), on 8:14
- minorityThe weight falls on downfall and judgment rather than on the physical act of tripping, so the phrase is best read as a judgment formula.; J.J.M. Roberts, First Isaiah (Hermeneia, Fortress, 2015), on 8:14
