Read the main article: Harmonizing the Exodus Sojourn
These tables supply the dates and calculations behind the main article. I retain the normal Masoretic Text (MT) chronology: 430 years in Egypt, from 1876 to 1446 BC, with Nisan reckoning. The comparisons do not require the additional 60 years associated with Terah or a second Cainan.
All dates are BC. An interval is the earlier, larger BC number minus the later, smaller number. The Exodus remains 1446 BC and the Conquest 1406 BC throughout.

A1. What the 430 years include
The question is where the counted sojourn begins. The normal MT reading counts Jacob’s household’s residence in Egypt. Readings that include Canaan allow the starting event to move earlier in the family’s story while retaining the same 430-year total.
On a narrow screen, scroll the table sideways to see every column.
| Reading | Starting event at 1876 BC | Division ending at the Exodus | Years in Egypt |
|---|---|---|---|
| Normal MT: 430 in Egypt | Jacob enters Egypt | 1876 → 1446 = 430 | 430 |
| 215 + 215 | Abram’s call from Haran to Canaan | 1876 → 1661 → 1446 = 215 + 215 | 215 |
| Localized 33 + 397 | Jacob returns from Haran | 1876 → 1843 → 1446 = 33 + 397 | 397 |
The first 215 years in the shorter reading come from three age statements. Abram is 75 at his departure from Haran and 100 when Isaac is born; Isaac is 60 when Jacob is born; Jacob is 130 when he enters Egypt (Genesis 12:4; 21:5; 25:26; 47:9):
(100 − 75) + 60 + 130 = 25 + 60 + 130 = 215.
In the normal chronology this family interval is 2091–1876 BC, preceding the Egyptian 430. In the shorter chronology it becomes 1876–1661 BC, leaving another 215 to the Exodus. The Samaritan Pentateuch’s broader wording supplies the interpretive setting; the number 215 is derived from these ages. Here “Canaan” names the patriarchal phase of the comparison: Jacob’s twenty years in Haran fall within it, so it does not mean uninterrupted residence in Canaan.
The localized reading counts the family’s Canaan residence after Jacob’s return: 130 − 97 = 33 years. Egypt then receives 430 − 33 = 397 years. The Greek wording’s inclusion of Canaan permits this interpretation; it does not itself specify that division.
The common 1876 date therefore names three different events. A fixed 1446 endpoint and a 430-year total produce the common starting date arithmetically. These three rows by themselves are not three independent demonstrations of a wider chronological pattern.
A2. The patriarchal dates and Jacob’s movements
The second column below is the normal chronology. The next is the MT minimum, or −215 sojourn comparison: the earlier patriarchal dates move 215 years later, while the Exodus and Conquest remain fixed. The “Localized: 397 Egypt” column applies the separate localized −33 interpretation to the normal patriarchal dates. The two adjustments answer different questions and are displayed separately.

| Event | Normal MT: 430 Egypt | MT minimum: 215 Egypt | Localized: 397 Egypt | Jacob’s age |
|---|---|---|---|---|
| Abram’s birth | 2166 | 1951 | 2133 | — |
| Abram’s call | 2091 | 1876 | 2058 | — |
| Isaac’s birth | 2066 | 1851 | 2033 | — |
| Jacob’s birth | 2006 | 1791 | 1973 | 0 |
| Flight to Haran | 1929 | 1714 | 1896 | 77 |
| Joseph’s birth | 1915 | 1700 | 1882 | 91 |
| Return from Haran | 1909 | 1694 | 1876 | 97 |
| Entry into Egypt | 1876 | 1661 | 1843 | 130 |
| Jacob’s death | 1859 | 1644 | 1826 | 147 |
| Levi’s death | 1782 | 1567 | 1749 | — |
| Exodus | 1446 | 1446 | 1446 | — |
| Conquest | 1406 | 1406 | 1406 | — |
Jacob’s age at flight can be reconstructed through Joseph. Joseph is 30 before Pharaoh; seven years of plenty and two of famine make him 39 at the family’s entry (Genesis 41:46; 45:6). Jacob is then 130, so he was 130 − 39 = 91 at Joseph’s birth. Joseph’s birth closes fourteen years of service; 91 − 14 = 77 at flight, and 77 + 20 = 97 at return (Genesis 30:25; 31:41).
Jacob’s final seventy years divide into 20 in Haran + 33 after returning to Canaan + 17 in Egypt. His return-to-death interval is therefore 50 years. The 70 years begin with his flight, not his return.
In the current canonical treatment, the localized −33 extends through Terah to Abraham, Jacob, and Levi. Terah’s inclusion is a structural scope decision; the 33-year derivation comes from Jacob’s family. The table displays the relevant patriarchal portion. No general backward extension of −33 is needed here.
The 215 reading also leaves Terah’s separate question intact: in MT without the additional 60 years, his death is 1816 BC, whereas Abram’s call is 1876 BC. A death at 1876 requires the MT +60 Terah state, 2081–1876, or the distinct Samaritan 145-year lifespan, 2021–1876. These are separate comparisons, not assumptions of the table.
A3. Jacob’s two seven-year service periods
The three boundaries are the beginning of service, the end of its first seven years, and the end of fourteen years. Genesis 29:27–30 places Rachel’s marriage after Leah’s bridal week, with the second seven-year obligation still to be fulfilled. Thus these dates mark service periods, not two weddings seven years apart.
On a narrow screen, scroll the table sideways to see every column.
| Reading | Service boundaries, BC | Destination | Intervals to that destination |
|---|---|---|---|
| Normal MT | 1929, 1922, 1915 | Exodus, 1446 | 483, 476, 469 = 69, 68, 67 sevens |
| MT minimum −215 | 1714, 1707, 1700 | Conquest, 1406 | 308, 301, 294 = 44, 43, 42 sevens |
| Localized −33 | 1896, 1889, 1882 | Conquest, 1406 | 490, 483, 476 = 70, 69, 68 sevens |
For example, 1929 − 1446 = 483 = 69 × 7. Subtracting 215 from the service dates gives 1714 − 1406 = 308 = 44 × 7; subtracting 33 instead gives 1896 − 1406 = 490 = 70 × 7.
The destination changes from Exodus to Conquest between rows. Once one boundary aligns with whole sevens, the other two necessarily do so because they are already seven years apart. The interest lies in the relationship between the sequences and their named destinations.
A4. Joseph’s plenty and famine: a companion check
Joseph’s normal birth date, 1915 BC, places his appearance before Pharaoh at 1915 − 30 = 1885 BC. Seven years of plenty end in 1878; seven years of famine end in 1871. Jacob’s 1876 entry falls two years into that famine. The other sequences follow by subtracting 215 or 33 from these boundaries.
On a narrow screen, scroll the table sideways to see every column.
| Reading | Plenty begins / famine begins / famine ends, BC | Intervals to Exodus 1446 |
|---|---|---|
| Normal MT | 1885, 1878, 1871 | 439, 432, 425: not whole sevens |
| MT minimum −215 | 1670, 1663, 1656 | 224, 217, 210 = 32, 31, 30 sevens |
| Localized −33 | 1852, 1845, 1838 | 406, 399, 392 = 58, 57, 56 sevens |
This table holds the Exodus endpoint constant. The normal sequence also gives 479, 472, 465 to the Conquest, again not whole sevens. Consequently, the comparison supports the stated alignments in the two alternative readings; it does not establish that every sequence aligns with either Exodus or Conquest.
A5. The localized 490-year coda
The localized interpretation gives a further relationship between Jacob’s flight, the deaths of Jacob and Levi, and the Conquest:
On a narrow screen, scroll the table sideways to see every column.
| Interval | Dates, BC | Years |
|---|---|---|
| Jacob’s flight to Jacob’s death | 1896 → 1826 | 70 |
| Jacob’s death to Levi’s death | 1826 → 1749 | 77 |
| Levi’s death to the Conquest | 1749 → 1406 | 343 |
| Jacob’s flight to the Conquest | 1896 → 1406 | 490 |
Thus 70 + 77 + 343 = 490, or 147 + 343 = 490. The final 343 is 7 × 49, seven jubilee measures; the whole 490 is 10 × 49.
The first 147 runs from Jacob’s flight to Levi’s death. It equals Jacob’s own 147-year lifespan numerically, while joining different endpoints. Jacob’s actual lifespan in this reading is 1973–1826 BC.
I read the resulting 70 × 7 as a Danielic resonance, recalling the seventy sevens of Daniel 9. The calculation is exact within the localized chronology; its association with Daniel is a typological reading. It adds a reason to examine this secondary interpretation while the normal MT chronology remains the starting point.

Exodus 12:40–41: text and translation
The side-by-side quotations in the main article are fresh English translations of the specified Hebrew and Greek texts, rather than quotations from a modern English Bible. The shared English wording makes the textual differences easier to see. Hebrew’s “thirty years and four hundred years” is rendered 430 years; “children of Israel” is retained throughout. The Hebrew divine name is represented by LORD. “Companies” renders the Hebrew plural for hosts; “entire force” reflects the Greek collective singular.
- MT: Mechon Mamre’s Hebrew text, Exodus 12:40–41. Verse 40 names Egypt. Verse 41 includes the same-day statement.
- SP: STEP Bible’s Samaritan Hebrew text, Exodus 12. Its edition information identifies a Kennicott-based transcription checked against von Gall. Verse 40 explicitly includes the fathers and names Canaan before Egypt; verse 41 agrees in wording with MT.
- LXX: Rahlfs–Hanhart, Septuaginta, second revised edition (2006), published online by the German Bible Society. Verse 40 names Egypt before Canaan. Its printed text does not include the fathers; verse 41 lacks the Hebrew same-day clause. The quotation follows this identified edition, rather than combining readings from different Greek witnesses.
Greek witnesses vary. Codex Alexandrinus adds “they and their fathers” after Canaan in verse 40, as recorded in Swete’s apparatus, vol. 1 (1887), p. 128. That addition is not part of the Rahlfs–Hanhart text quoted in the main table.
The inclusion of Canaan supplies the textual setting for the alternative chronologies. Their divisions still require interpretation and the Genesis age calculations in A1; the verses themselves do not specify either split.
The original Sojourn discussion preserves the wider exploration from which this focused comparison developed.
