The genealogies of Jesus place the promises to Abraham within the story that leads to Christ. Read alongside Israel’s departure from Egypt and entrance into Canaan, their numerical arrangements offer a way to connect ancestry with deliverance and inheritance.
The clearest comparison begins with the Conquest as a center. In the 70-year genealogical model, Matthew’s 42-period arrangement has equal spans on either side of 1406 BC. A defined adjustment brings the corresponding center to the Exodus in 1446 BC. Luke supplies a wider setting, in which the Creation-to-Conquest chronology of the Book of Jubilees occupies a balanced central block.
These are comparisons within the chronological model. The Gospel texts supply the names and their arrangement; they do not assign every ancestor a 70-year lifespan. The introduction, counted-name tables, and Part 1 detailed study explain that foundation.
1. Moses and the forty-year interval
Two biblical age notices frame the comparison:
Moses was eighty years old and Aaron was eighty-three when they spoke to Pharaoh.
Moses was a hundred and twenty years old when he died, yet his eyes were not weak, and his vitality had not diminished.
The difference is 120 − 80 = 40 years. The normal Nisan-based Masoretic Text (MT) chronology used here places the Exodus in 1446 BC and Moses’ death and the Conquest transition in 1406 BC. This ordinary chronological interval is the reference against which the schematic comparisons are measured.
The genealogical model uses 6 BC as its nativity hinge. Completing a 70-year period from that hinge reaches AD 65, because civil BC–AD reckoning has no year zero: 6 + 65 − 1 = 70. AD 65 is a model boundary, not Jesus’ death date.
All calculations below use ordinary elapsed-year arithmetic. The equal 70-year assignments are schematic; they are neither the Rounded Chronology nor sums of actual patriarchal lifespans. No Mirror operation is involved.
2. The Conquest at the center of Matthew’s arrangement
Matthew’s three groups of fourteen supply 42 occupied positions in the adopted Jeconiah-overlap reading. The same Jeconiah occupies a place on each side of the exile boundary; there are still 41 distinct figures in the continuing male line. Assigning 70 years to each occupied position and completing the last period at AD 65 gives an opening bracket at 2876 BC.
The Conquest divides this span exactly:
2876 − 1406 = 1470 years.
1406 + 65 − 1 = 1470 years.
Each half contains 21 × 70, or 30 jubilees of 49 years. The whole is 2940 = 42 × 70.

Two ways of counting; the same Conquest center
Matthew’s 70-year model retains 1406 BC as its midpoint in both counting states.
42 occupied periods · 2940 years
Remove 70 years at each end: the central boundary stays in place.
40 adjacent intervals · 2800 years
These are schematic 70-year periods and adjacent intervals, not biological lifespans.
Schematic arrangement; node spacing is not to scale. Civil BC/AD reckoning has no year zero: a cross-era span is BC + AD − 1.
The center also survives a more restricted measurement. Remove the 70-year extension supplied by the overlap, and stop at Jesus’ opening boundary rather than completing his allocated period. Both ends move inward by 70 years. The resulting span is 2806 BC → 6 BC, with 1400 years on either side of 1406 BC.
This distinction matters: 42 completed periods and 40 intervals between 41 figures are different measurements. Their shared center follows from shortening the two ends equally. File 69 §3.4D develops the comparison. The exact endpoint table below keeps the two states separate.
3. A parallel branch through Levi
The same 70-year framework can display the line Abraham → Isaac → Jacob → Levi → Kohath → Amram → Moses. This is a parallel comparison through Levi. Matthew’s own genealogy continues through Judah; Moses is not inserted into its printed list.
Beginning at the 2876 BC bracket and assigning a full period to each of these seven figures produces:

Source: File 69 §3.4D. These are allocated model periods, not reconstructed birth and death dates.
Seven completed periods span 490 years, bringing the branch to 2386 BC. From that generated Moses-period close to the ordinary Conquest anchor is another 980 years, or fourteen 70-year periods:
2876 → 2386 → 1406 BC = 490 + 980 = 1470.
The left half of Matthew’s larger comparison therefore divides into 7 + 14 periods. This makes the Mosaic connection concrete while preserving both chronologies: 2386 BC is the branch’s schematic close, and 1406 BC remains the ordinary Moses-death/Conquest anchor.
4. From the Conquest center to the Exodus center
The next relationship uses the 110-year boundary adjustment developed in File 68 §§6.3–6.3B and applied to Matthew in File 69 §3.4D. Its biblical context includes the 110-year lives of Joseph, Genesis 50:26 BSB, and Joshua, Joshua 24:29 BSB. Using that value as an adjustment is a rule of the research model; the lifespan notices themselves do not instruct us to shift a genealogy.
The operation can be followed at both ends. Start with the undoubled Abraham boundary and move it 110 years earlier:
2806 + 110 = 2916 BC.
At the other end, the model’s second 70-year period closes at AD 135, one period after AD 65. Move that boundary 110 years earlier:
AD 135 − 110 = AD 25.
The resulting span is 2916 BC → AD 25. Its total is still 2940 years, but its midpoint is now 1446 BC:
2916 − 1446 = 1470; 1446 + 25 − 1 = 1470.

A defined boundary adjustment centers the Exodus
The 110-year operation produces a second 2940-year envelope, centered 40 years earlier.
Conquest-centered envelope
110 − 70 = 40: each boundary moves 40 years earlier.
Exodus-centered envelope
1470 + 1470 = 2940 = 42 × 70
AD 25, AD 65 and AD 135 identify model boundaries; no historical events are assigned to them here.
Schematic arrangement; node spacing is not to scale. Civil BC/AD reckoning has no year zero: a cross-era span is BC + AD − 1.
The controlling difference is easy to remember: 110 − 70 = 40. Relative to the original 2876 BC–AD 65 span, both endpoints and the center stand 40 years earlier. The model moves from the Conquest center to the Exodus center by the same interval that separates those events in the ordinary chronology.
The parallel Levi branch moves with it: 2916 → 2426 → 1446 BC, again 490 + 980. The adjustment applies to the boundaries once; it does not add 110 years to every generation. AD 25 and AD 135 retain their roles as generated endpoints here. Neither is assigned a new historical or future event.
5. Luke’s wider frame: thirty, fifty, thirty jubilees
Luke’s full model opens at 5326 BC and closes at AD 65. It contains 77 allocated periods of 70 years, including a figurative opening position labelled “God.” That label reflects Luke’s conclusion and does not assign God an age or origin.
The count uses the single Ram/Aram form of Luke 3:33, with the second Cainan retained: 76 human figures, including Jesus, plus the figurative opening. The BSB prints Admin and Arni in that part of the list and therefore has an additional position. The edition comparison displays the distinction directly.
Within this wider span, File 54 §§8.6 and 13.2 places the Book of Jubilees (BJ) Creation-to-Conquest chronology at the center:
Gospel genealogies · Figure 3
Fifty jubilees at the center
The Book of Jubilees’ Creation-to-Conquest span occupies the middle of Luke’s complete 77-period model.
Three connected spans · 30 + 50 + 30 jubilees

35 × 70
21 × 70
5390 years = 110 × 49 = 77 × 70
The equal outer spans frame the central 2450 years.
The Lukan model uses 76 human figures plus the figurative “God” position, with a single Ram/Aram sequence and the second Cainan retained. Book of Jubilees Creation is a distinct chronological state from ordinary MT Creation.
Schematic arrangement; node spacing is not to scale. Civil BC/AD reckoning has no year zero: a cross-era span is BC + AD − 1.

| Whole span | 5390 | 110 | 77 |

The central block is 2450 = 50 × 49, flanked by equal spans of 1470 = 30 × 49. In 70-year units the same arrangement reads 21 + 35 + 21. The symmetry is visible in either measure, although a 49-year jubilee remains distinct from a 70-year model period.
BJ’s 3856 BC Creation belongs to its own chronology; it does not replace the normal MT Creation at 4114 BC. Likewise, Luke’s 5326 BC opening is generated by the equal-period model. The comparison brings these separately defined constructions together around the Conquest without merging their event labels.
The balanced arrangement supports a reading of the genealogy alongside jubilee traditions of promise, judgment, and inheritance. It does not by itself establish that Luke directly used the Book of Jubilees or consciously calculated these BC dates.
6. What these connections show
The useful pattern is a relationship among whole arrangements. Matthew’s model places the Conquest at an exact center; its defined 110-year adjustment moves that center to the Exodus. Luke’s wider model gives the BJ Creation-to-Conquest span equal jubilee measures on either side.
Together, these comparisons keep attention on the biblical movement from promise through deliverance to inheritance. Their arithmetic is exact under the stated rules. Their theological value lies in how the structures illuminate that movement, with the Gospel wording, the ordinary chronology, and the schematic calculations each retaining their own role.
Supporting endpoint table
For two BC dates, subtract the later label from the earlier. For a span crossing into AD, use BC + AD − 1. All rows below use that civil convention.
