The Origin
Kairos Biblia began as a private inquiry — a question that refused to stay quiet: what if the Hebrew calendar is not merely a liturgical heritage, but a prophetic architecture? What if the appointed times of Leviticus 23 were designed from the outset to map, with precision, onto events that would unfold across millennia?
Sem and Lulu came to this question from different directions but arrived at the same conviction: the internal logic of Scripture is coherent, dateable, and far more structurally sophisticated than it is usually given credit for. The work began with the feasts. It expanded into chronology. It kept opening.
These are the appointed times of the LORD — holy convocations — which you shall proclaim at the times appointed for them.
Leviticus 23:4
What We Do
Our work sits at the intersection of three disciplines: biblical chronology, typological exegesis, and Hebrew calendar mechanics. We treat these not as separate specialties but as a single integrated method — because the texts themselves refuse to be siloed.
A date in 1 Kings illuminates a feast in Leviticus. A feast in Leviticus illuminates a morning in a Jerusalem garden. That garden morning illuminates a harvest feast fifty days later. The whole moves as one.
Chronology
Fixed dates, internal consistency, and the logic of the 480-year anchor in 1 Kings 6:1
Typology
Structural correspondences between Exodus events, Levitical feasts, and New Testament fulfillments
Calendar
Hebrew reckoning, evening-to-evening days, the Omer count, and the nine moedim of Leviticus 23
Our Chronological Anchors
Every framework needs fixed points. Ours are not chosen for convenience — they emerge from the texts themselves and lock together with uncommon precision.
1 Kings 6:1 → 1446 BCE
The 480-year interval from the Exodus to the foundation of Solomon's Temple, read literally and synchronised with Egyptian chronology.
Passion Week → 30 CE
14 Nisan as Friday, confirmed by astronomical data for 30 CE — the only year in the plausible range that satisfies all the textual constraints.
17 Nisan → Resurrection
Bikkurim — the Feast of Firstfruits — falling on the precise day of the empty tomb, within the Omer window, as prescribed in Leviticus 23.
6 Sivan → Pentecost
Fifty days from Bikkurim, mirroring the Sinai theophany — and the 3,000 inversion between the golden calf judgment and the Acts 2 harvest.
Our Approach
We work with primary sources: the Hebrew and Greek texts, the Mishnah and relevant Talmudic tractates (particularly Yoma and Menahot), Josephus, and the astronomical record. Secondary scholarship is engaged seriously — we read the critical literature — but it does not set the terms of our inquiry.
Typology, for us, is a literary and theological category that the texts themselves employ. We do not impose correspondences; we follow the internal signals: the verbal echoes, the structural parallelisms, the calendrical alignments that the authors have embedded. The criterion is always: does the text indicate this, or are we projecting it?
A note on method
We distinguish rigorously between typology and allegory, and between structural correspondence and speculative numerology. Not every parallel is meaningful. The ones we develop meet specific exegetical criteria, laid out in full on the Methodology page.
The Books
The volumes we have written are the distillation of years of study — designed to be rigorous enough for the scholar and accessible enough for the serious lay reader. They are meant to be read in sequence but can also stand independently. Each book builds on a specific node of the framework: the appointed times, the Exodus chronology, the typological correspondences, the counter-system analysis.
The books are available through Lulu Press. Physical copies are in production; details will appear on the Books page as they become available.
