All of the land between the Nile and Euphrates Rivers.
The LORD made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates. Genesis 15:18 It's hard to tell what God had in mind here. Was this land given to all of Abraham's "seed" (including Ishmael and his descendants) or just to the descendants of Abraham's favorite son Isaac. I will set thy bounds from the Red sea even unto the sea of the Philistines, and from the desert unto the river. Exodus 23:31 (The "sea of the Philistines" is probably the Meditarranean Sea, but what is "the great river"? The Nile or the Euphrates?)

In that day Yahweh made a covenant with Abram, saying, “I have given this land to your offspring, from the river of Egypt to the great river, the river Euphrates:
I will set your border from the Red Sea even to the sea of the Philistines, and from the wilderness to the River; for I will deliver the inhabitants of the land into your hand, and you shall drive them out before you.
Examining the tension
What follows is one scholar’s way of reading this disagreement — a critical-historical view that often concludes the texts genuinely disagree. It draws on the peer-reviewed sources listed below and stands as one position among the answers above, presented for transparency, not as GEBible’s position.
How critical scholarship weighs this: Widely regarded as a genuine contradiction
This summarizes where critical scholarship tends to land on this tension — a report on the field’s center of gravity, not GEBible’s own ruling.
The biblical texts describe the land promised to Israel with at least three incompatible sets of boundaries. The covenant grant of Genesis 15:18, echoed in Exodus 23:31, runs from "the river of Egypt" to "the great river, the river Euphrates" — a vast Levantine swath. Numbers 34:1-12 maps a far smaller territory roughly coextensive with Canaan proper, bounded by the Wadi of Egypt, the Mediterranean, a northern line near Lebo-Hamath, and the Jordan/Dead Sea on the east. Ezekiel 47:13-21 draws a third map, with the northern border anchored near Damascus and Hamath and the southern at Tamar and the waters of Meribah-Kadesh. These are not the same territory.
The principal harmonization, articulated by Archer and by John Walton, treats Genesis 15 as the "ideal" or maximal grant, briefly approximated under David and Solomon, while Numbers 34 gives the realistic tribal allotment and Ezekiel 47 the eschatological restoration. The appeal is to different purposes rather than different boundaries of one promise. This is the strongest case, and it must be stated fairly: the texts do serve different functions, and 1 Kings 4:21 (MT 5:1) does describe Solomon ruling "from the River" to the border of Egypt.
The harmonization nonetheless strains against the texts' own self-presentation. Genesis 15:18 uses the formal language of an unconditional, perpetual grant — "unto thy seed have I given this land" — not the language of an aspirational ceiling. And 1 Kings 4:21 describes a sphere of tributary suzerainty ("they brought presents and served Solomon"), not occupation and settlement to the Euphrates; the verse itself distinguishes ruling over kingdoms from possessing their land. So even the one period adduced as fulfillment does not match the grant.
The boundary descriptions also turn on genuinely different geographical anchors, and a lexical contrast underlines the point. Genesis 15:18's southern boundary is *nehar Mitzrayim* — built on *nahar*, the term for a perennial river, the same word used for the Euphrates (*ha-nahar ha-gadol nehar Perat*) in the very same verse. Numbers 34:5 and the parallel boundary texts instead use *nachal Mitzrayim*, the "Wadi of Egypt" (Wadi el-Arish), a seasonal stream far short of the Nile. (The Nile itself is normally designated in Hebrew not by *nahar* but by *ye'or*, so the issue is not that *nahar* denotes the Nile, but that the grant tradition uses a perennial-river term where the allotment tradition uses a wadi.) The grant tradition's southern terminus, in other words, is described in language that points toward a major river, while the allotment tradition stops at a desert wadi — a difference of southern reference points that the maximal/minimal scheme cannot dissolve, since the two maps do not begin at the same anchor.
Critical scholarship reads the three maps as boundary traditions from different periods and sources. Moshe Weinfeld's study of the land promise argues that the Genesis 15/Exodus 23 grant reflects a Davidic-Solomonic imperial horizon, projecting the empire's tributary reach onto the patriarchal covenant. The Numbers 34 list is generally assigned to the Priestly stratum and reflects a (likely exilic or post-exilic) program defining the "true" Canaan, with borders that strikingly resemble the Egyptian province of Canaan in the Late Bronze Age. Ezekiel 47-48, dated to the early exile, is the prophet's programmatic vision of a restored and re-tribed land, idealized and schematic rather than descriptive. Each is internally coherent; together they describe three different countries.
The deeper problem the harmonization cannot reach is historical. As Israel Finkelstein, Weinfeld, and others note, no period in the archaeological record shows an Israelite or Judahite polity controlling territory matching any of the three maps, least of all the Euphrates grant. The borders are literary and theological constructs serving distinct agendas, not surveyors' records of a single bequeathed estate.
Where the critical reading lands: genuine contradiction reflecting three distinct border traditions; the maximal/minimal harmonization flattens the compositional layers and is contradicted by the differing southern anchors (perennial river vs. Wadi of Egypt) and by the historical record.
