Shared ground
These closing lines are a sobering afterword to Balaam’s speeches. Balaam reacts to what he foresees with distress (“Alas”) and a survival question: the coming events are so weighty that simply staying alive is in doubt. The text also places the decisive initiative with God (“when God does this”), even though the means described are human armies arriving by sea.
The oracle then sketches far-off maritime forces (“ships…from Kittim”) striking inland powers (“afflict Asshur…afflict Eber”). But it refuses to treat the sea power as unstoppable: the attacker “also…shall come to destruction.” The story then ends without further explanation—Balaam and Balak both leave, and the narrative hands the future over to time.
Where interpretation differs
Who/what is “Kittim”? Many readers take it as a general pointer to western, Mediterranean seafaring powers (starting with Cyprus and widening from there). Others argue the oracle is meant to point to a more specific later empire that arrived from the west by sea (often suggested: Greek or Roman power).
Who/what is “Eber”? Some read “Eber” as a broad regional label (“people across the river”), possibly including groups connected with early Israel’s wider ancestry. Others take it more narrowly as the Hebrews/Israel in some form, making the line sound like Israel will also feel the blow of these distant powers.
Who is the one that “also…shall come to destruction”? Most naturally it refers to the same sea-based aggressor just mentioned: the ships’ power brings suffering but does not last. A minority reading takes the “also” to point back to one of the afflicted parties instead, though the immediate flow favors the attacker being the one whose end is announced.
Why the disagreement exists
The place-names function partly as direction markers and broad ethnic labels rather than tight modern borders. “Kittim” can be both a specific island reference and a shorthand for the far-west maritime world. “Eber” can be used as a personal/ancestral name and as a wider label. Because the oracle is brief and unspecific about dates and identities, readers differ on whether it aims at a general pattern (“distant powers will strike, but fall”) or a pinpoint prediction of a later empire.
What this passage clearly contributes
It reinforces that God’s purposes are not limited to Moab’s immediate fear of Israel; the horizon expands to international upheavals. It also frames history as morally and politically unstable: even a terrifying aggressor from afar is not the final winner (“he also shall come to destruction”). Finally, the quiet departure of Balaam and Balak closes the episode without resolution on the ground, underscoring that the oracle’s fulfillment lies beyond the scene (Numbers 24:23–25).
