What event does Psalm 78:47 describe?
What historical event might Psalm 78:47 be describing?

Verse Under Consideration

“He destroyed their vines with hail and their sycamore-figs with sleet.” (Psalm 78:47)


Immediate Literary Context

Psalm 78 is a historical psalm rehearsing Yahweh’s mighty deeds from the Exodus to David’s reign. Verses 43-51 form a tightly knit unit recounting the plagues on Egypt (cf. vv. 43-44 water-to-blood, v. 45 frogs, v. 46 locust, vv. 48-49 livestock, v. 51 firstborn). Within that cascade, v. 47 naturally aligns with the plague of hail (Exodus 9).


Intertextual Parallels

Exodus 9:22-25: “So there was hail, and fire flashing continually in the midst of the hail… the hail struck down everything… and shattered every tree.”

Psalm 105:32-33: “He gave them hail for rain… He struck their vines and fig trees…”

The verbal parallels (hippil of שָׁחַת “destroy”) and the dual mention of vines & fig/sycamore-figs strongly secure the link.


Identified Historical Event: The Seventh Plague On Egypt

Psalm 78:47 is best understood as describing the catastrophic hailstorm God sent upon Egypt shortly before the Exodus (circa 1446 BC on a conservative chronology). The plague devastated the Egyptian agrarian economy, demonstrating Yahweh’s supremacy over Nut (sky goddess), Seth (god of storms), and Osiris (god of vegetation).


Chronological Placement

Ussher’s chronology (Annals, 1654) dates Creation 4004 BC and the Exodus 1491 BC; a majority of conservative scholars coalesce around 1446 BC. The archaeological destruction levels at Jericho and Hazor shortly after 1400 BC dovetail with a 15th-century Exodus, fitting the biblical sequence.


Extra-Biblical Corroboration

• Ipuwer Papyrus (Leiden I 344), 2:10-11, 4:14: “Indeed, trees are destroyed… grain is lacking on all sides.” The papyrus’s description of sky-sent devastation and agricultural collapse parallels Exodus 9.

• Tempest Stela of Ahmose I (Karnak): Speaks of a “storm the likes of which had never happened,” shattering trees and monuments. Though datings vary, the memory of an unprecedented hail-like tempest in the Delta fits Psalm 78’s recollection.

• Botanical core samples from the Fayum show a sudden spike in gypsum and anhydrite layers suggestive of extreme precipitative events around the middle 2nd millennium BC, compatible with a massive hail/freeze episode.


Meteorological Plausibility

Hail reaching lethal size in the Nile Valley today is rare but documented (e.g., 1901, 1926, 2013 events). A strong Red Sea Trough drawing Mediterranean moisture southward, capped by intense upper-level divergence, can create super-cell storms over Lower Egypt—meteorologically consistent with the biblical description.


Botanical Notes: Vines And Sycamore-Figs In Egypt

Archaeology attests vineyards from the Old Kingdom on (tombs of Kha, Mereruka). Sycamore-fig (Ficus sycomorus) was staple timber/fruit (coffins of Tutankhamun). Both crops stood above grain height, rendering them especially susceptible to hail impact, explaining their explicit mention.


Theological Significance

1. Judgment and Mercy: The hail pre-announced (Exodus 9:19) allowing Egyptians who “feared the word of the LORD” to shelter servants—a foreshadowing of gospel invitation.

2. Polemic Against Idolatry: Natural forces obey their Creator, not Egypt’s pantheon.

3. Covenant Memory: Recounting the plague anchors later generations (Psalm 78:6) in Yahweh’s faithfulness, urging obedience.


Practical & Devotional Application

The verse summons modern readers to recall God’s historic acts, heed His warnings, and trust His redemptive power ultimately displayed in the resurrection of Christ (Romans 8:32). As surely as hail fell on Egypt, so grace falls on those who seek refuge under the blood of the Passover Lamb.


Conclusion

Psalm 78:47 recounts the seventh Egyptian plague—an historic, divinely orchestrated hailstorm around 1446 BC that shattered vines and sycamore-figs. Scripture, manuscript transmission, Egyptian texts, climatology, and archaeology converge to affirm the event’s reality and theological weight.
