These tables explain the fourteen-year comparison in the normal MT/Nisan framework, with 430 years in Egypt, no +60 Terah, and no restored second Cainan. All dates below are BC. Same-era intervals use the larger, earlier BC label minus the smaller, later one. Actual lifespans are retained; this is not the Rounded Chronology.

A1. The textual inputs and regular dates
On smaller screens, scroll a wide table horizontally to see every column.
| Person | Age or lifespan used | Biblical source |
|---|---|---|
| Levi | 137 | Exodus 6:16 |
| Kohath | 133 | Exodus 6:18 |
| Amram | 137 | Exodus 6:20 |
| Moses before Pharaoh / Exodus comparison | 80 | Exodus 7:7 |
| Moses, complete life | 120 | Deuteronomy 34:7 |
| Jacob, for the fourteen-year lifespan comparison | 147 | Genesis 47:28 |
| Aaron, for the fourteen-year lifespan comparison | 123 | Numbers 33:39 |
The entries above are calculation figures, not rewritten quotations. In particular, BSB prints “eighty” and “eighty-three” in Exodus 7:7; the main article preserves its quoted passages’ wording and number formatting.
The selected regular dates are reconstructed coordinates in this chronology, rather than dates printed in Scripture:
| Event | BC date | Relevant check |
|---|---|---|
| Levi’s birth | 1919 | 1919 − 1782 = 137 |
| Jacob’s household enters Egypt | 1876 | Levi is 1919 − 1876 = 43 |
| Levi’s death | 1782 | 1876 − 1782 = 94 after the Entry |
| Moses’ birth | 1526 | 1526 − 1446 = 80 |
| Exodus | 1446 | 1876 − 1446 = 430 |
| Moses’ death / Conquest | 1406 | 1526 − 1406 = 120 |
File 61 §§1.1, 1.5 and 6.3–6.5 controls this regular comparison; File 18 §§2.3–2.4 supplies the regular table framework. Its minimum Levi row 1704–1567 becomes 1919–1782 after the stated +215 sojourn placement. Neither Exodus nor Moses moves with that adjustment. The broader sojourn distinctions are explained in the sojourn article.
A2. What the three sums mean
| Starting point | Formal consecutive sum | Regular interval to Exodus | Difference |
|---|---|---|---|
| Levi’s birth | 137 + 133 + 137 + 80 = 487 | 1919 − 1446 = 473 | 14 |
| Entry | 94 + 133 + 137 + 80 = 444 | 1876 − 1446 = 430 | 14 |
| Levi’s death | 133 + 137 + 80 = 350 | 1782 − 1446 = 336 | 14 |
The first row becomes the second by removing 43 from both sides. The second becomes the third by removing 94. Thus these are three presentations of the same residual, not three independent confirmations.
File 61 §§6.3–6.6 calls these maximum non-overlap lifespan envelopes. “Maximum” belongs to the artificial arrangement that places the full lives consecutively. It is not a historically admissible upper bound after every narrative constraint has been imposed.
Genesis 46:11 lists Kohath among those entering Egypt. Consequently, the Entry row cannot mean that Levi lives his remaining 94 years and then the historical Kohath begins his entire life. Even allowing Kohath all 133 years after Entry, the uninterrupted named succession Kohath–Amram–Moses would supply at most 133 + 137 + 80 = 350 before allowing for overlap. The fourteen-year comparison therefore does not settle the genealogical problem of the full Egyptian 430 years. It compares the formal lifespan ledger with the adopted regular chronology, leaving the omitted begetting ages unresolved.
This distinction preserves both the numerical observation and the textual constraint. The broader proposal that the omitted ages intentionally permit complementary chronological readings is identified as an interpretive hypothesis in File 61 §6.2.
A3. Building the cumulative positions
Work backward from Moses’ death/Conquest at 1406, adding each full lifespan:
| Step | Calculation | Resulting cumulative boundary |
|---|---|---|
| Moses | 1406 + 120 = 1526 | Moses’ birth, the fixed lower anchor |
| Amram | 1526 + 137 = 1663 | Beginning of Amram’s cumulative block |
| Kohath | 1663 + 133 = 1796 | Beginning of Kohath’s cumulative block |
| Levi | 1796 + 137 = 1933 | Beginning of Levi’s cumulative block |
| Jacob | 1933 + 147 = 2080 | Beginning of Jacob’s cumulative block |
The earlier boundaries are positions in the cumulative construction. In particular, 1796 and 1663 do not claim to date Kohath’s and Amram’s historical births. File 18 §6A and File 61 §§1.2–2.1 supply this Moses/Nisan line. The cumulative introduction explains the method in its full ancestral setting.
A4. Original, halfway, and fourteen-year placements
The local translation is T14(C) = C − 14. Its exact midpoint is H7(C) = C − 7. Subtraction moves a BC coordinate forward in time. These operations generate comparison positions; they do not revise the original cumulative table.
| Cumulative boundary | Original C | Halfway H7 | Full T14 |
|---|---|---|---|
| Abraham | 2435 | 2428 | 2421 |
| Isaac | 2260 | 2253 | 2246 |
| Jacob | 2080 | 2073 | 2066 |
| Levi | 1933 | 1926 | 1919 |
| Kohath | 1796 | 1789 | 1782 |
| Amram | 1663 | 1656 | 1649 |
| Moses-side terminal / fixed-birth interface | 1526 | 1519 | 1512 |
Successive intervals in every column remain 175, 180, 147, 137, 133, 137. The last row’s 1519 and 1512 are derived interfaces measured from Moses’ fixed birth in 1526, not replacement births. Exodus 1446 and Conquest 1406 remain fixed.
The particularly clear landing is 1933→1796 = 1919→1782 = 137: the translated cumulative Levi block coincides with regular Levi’s full life. Farther down, 1782→1649 = 133 and 1649→1512 = 137 are formal successive lifespan blocks only. They retain Kohath’s and Amram’s lengths without supplying their historical birth dates.
Sources: File 61 §§7.3A, 8.1–8.4; File 62 §§1.1–1.5 and 2.4. The declared local translation extends through the Abraham–Moses portion shown; it is not a global −14 chronology variant.
A5. Moving one boundary and moving both
For a block P − S = L, moving the earlier boundary alone gives (P − 14) − S = L − 14. Moving the later boundary as well restores the full length: (P − 14) − (S − 14) = L.
| Block | Original length | Earlier boundary moved alone | Both boundaries moved |
|---|---|---|---|
| Abraham → Isaac | 175 | 161 | 175 |
| Isaac → Jacob | 180 | 166 | 180 |
| Jacob → Levi | 147 | 133 | 147 |
| Levi → Kohath | 137 | 123 | 137 |
| Kohath → Amram | 133 | 119 | 133 |
| Amram → Moses-side boundary | 137 | 123 | 137 |
| Moses → Exodus | 80 | 66 | Exodus stays fixed: 80 = 14 + 66 |
This is File 61 §7.4’s complete set of one-boundary results, including 166 and 119. No special meaning is assigned to every output. The main article’s Levi example uses the equal movement of both boundaries, which preserves 137.
A6. The narrative double sevens
| Narrative period | Selected normal dates, BC | Division | Text |
|---|---|---|---|
| Jacob’s service for his wives | 1929→1922→1915 | 7 + 7 = 14 | Genesis 29:27–30; 31:41 |
| Joseph’s plenty and famine | 1885→1878→1871 | 7 + 7 = 14 | Genesis 41:29–30 |
The first row marks periods of service. Rachel’s marriage follows Leah’s bridal week, with the second seven-year obligation still to be fulfilled; the table does not place the two weddings seven years apart. Jacob’s return from Haran is later, in 1909 BC.
File 61 §7.2 supplies the fourteen-year narrative comparisons. The lifespan differences 147 − 133 = 14 and 137 − 123 = 14 are set out in File 62 §2.2. These support the interpretation of the pattern; they are not additional adjustments to the dates.
A7. Keep the different uses of seven distinct
The H7 midpoint moves a chosen cumulative position seven years forward: Levi 1933→1926. A seven-year cumulative envelope is a separate range of starting positions in File 18 §6A—for example, Levi 1938–1931, Kohath 1801–1794, and Amram 1668–1661. Those ranges are not uncertainty estimates for historical births, and H7 is not another name for an envelope endpoint.
The separate exact Aaron/Tishri branch stands 3.5 years earlier than the selected Moses/Nisan positions. File 62 §1.3 gives its full parallel table; the interval pattern is preserved there too. Whole-year displays, exact half-year phases, normalized seven-year ranges, and 7.5-year cross-phase spans retain their own meanings. The main article needs only the selected Moses/Nisan line and its equal seven-year steps.

Files 61–62 continue into Joseph’s double portion, the birth-law comparisons, and the wider cumulative structure. Those studies can be followed from the canonical sources without making them prerequisites for the present fourteen-year explanation. The extended study offers further discussion; the current canonical files control the chronological settings used here.
