Asaf (my scribe) has gotten his micrography for the tefillin letters to almost the right size of about 1 mm in height.

To the right is a close-up of one of the tefillin slips from Wadi Murabbaสฟat; to the left, Asaf's writing with a reed on the flesh side of the papillary dermis of a goat.

If the Julius-Wellhausen-Vorlesung was too formal for your tastes, here I take off the tie and vest and sit down in the lab with Alex for a friendly one-on-one.

Professor Ken Gemes reached out a few weeks ago to inform me that he was planning to give this online lecture, presenting my work in The Origins of Judaism.
This led to a wonderful exchange over email.

Prof. Gemes comes at this from his own fieldโ€”philosophy (he specializes in Nietzsche).

Alex Tseitlin just stopped by for a lovely conversation on when Jews began to identify as "Israel".
The interview will appear soon on his Kedem Channel, over at YouTube.
Stay tuned!

Adriano Virgili has just published on his blog (in Italian) an excellent review of my new book, Between Yahwism and Judaism.
He does a superb job distilling the main themes and arguments into a clear and thoughtful summary. Itโ€™s the first review to appear, and I was truly delighted to read it.

Prof. Aren Maeir just published an excellent response to recent pieces in Haaretz by Ofri Ilany and Elon Gilad on when โ€œJudaismโ€ first emerged.

I had considered penning a response myself, but Prof. Maeir beat me to it.

It would appear that this letter was meant to answer the acute quandary plaguing first-century communities of Gentile Jesus-followers as to whether they too should be observing the various dietary restrictions commonly adhered to by Jews.

This instruction to Noahโ€™s family, as the progenitors of all humanity, was apparently taken as applicable not only to Jews but to Gentiles as well.

The source for the instruction in Acts seems to be Godโ€™s pronouncement in Gen 9:3โ€“4 addressed to Noah and his sons: โ€œEvery moving thing that lives shall be food for you; and just as I gave you the green plants, I give you everything...

Thus Philo (Spec. Laws 4:122), who condemned the decadent people who: โ€œdevise novel kinds of pleasure and prepare meat unfit for the altar by strangling and throttling the animals, and entomb in the carcass the blood which is the essence of the soul and should be allowed to run freely away.โ€

...and from blood and from what is strangled [ฯ€ฮฝฮนฮบฯ„แฟถฮฝ] and from fornication. If you keep yourselves from these, you will do well.โ€

The meat of a strangled animal was likely regarded as infused with prohibited blood, as strangling kills the animal without shedding any blood.

The laws thought to have been given to the โ€œchildren of Noahโ€ seem to make an appearance in the New Testament.
