Shared ground
This passage presents the locust plague as an event Yahweh initiates through Moses’ acted signal. The stated goal is specific: the locusts will consume what the hail did not destroy. The story also links Yahweh’s action with a natural means—an east wind that blows through the day and night and brings the swarm by morning.
The language is intentionally totalizing. Repeated “all” language, “over all the land,” and “nothing green remained” make the reader feel the scale and completeness of the loss across Egypt.
Where interpretation differs
Some readers take “no such locusts before…nor after” as a literal, once-in-history claim about locust intensity. Others understand it as ordinary disaster language: the worst anyone could remember, stated in absolute terms to stress severity.
Some also weigh “covered the surface of the whole earth” differently. Many read “earth” here as “land,” meaning the land of Egypt in view. Others hear a more global-sounding claim, though the surrounding sentences keep the focus on Egypt’s territory.
A third difference is how people relate Yahweh’s role to the wind. Some read the wind as the mechanism Yahweh uses (Yahweh directs the wind, and the wind carries locusts). Others emphasize a more direct divine intervention with the wind functioning as a narrative sign of Yahweh’s control.
Why the disagreement exists
The disagreement comes from how absolute phrases are handled in ancient narrative (“never before/after,” “whole earth”) and from how the text blends divine agency with ordinary weather. The passage explicitly states both (Yahweh acts; wind blows) without explaining the relationship in philosophical detail.
What this passage clearly contributes
Explicitly, the text claims: Yahweh instructs Moses to signal; Moses does; Yahweh brings an east wind; the wind brings the locusts; the locusts cover Egypt and settle throughout its borders; they consume every remaining plant and fruit after the hail until nothing green remains. Theologically by inference, the passage contributes a picture of Yahweh’s control over timing (“morning”), means (wind), and scale (“all Egypt”), and it portrays the plagues as targeted escalation rather than random disaster—this one completes the agricultural ruin begun by hail (Exodus 10:12).
