The Mossad was unsuccessful, but where they failed, Bible scholars succeeded. That ancient manuscript was the Bible. Enough to ruffle the hairs under more than a few kippot in the Orthodox Jewish community which traditionally believes that every letter, jot and tittle of the Torah we read today is identical to those that were transmitted to Moses at Mount Sinai. The Ben-Asher text was used by scribes who wanted to write a copy of a Torah scroll. The former allows a scribe to quickly flip to a desired page, with the latter he has to roll it.
Books are also cheaper to make because both sides of the page are used.
This Ben-Asher book eventually made its way to Cairo, where the great theologian Maimonides copied from it when he wrote his own Torah scroll. And, in Maimonides' magnum opus of Jewish legal writings, he attests that this book is the most authentically accurate manuscript of the Bible. In December 1947, after the United Nations voted for partition and to create Israel, the Arabs of Aleppo rioted, destroying the synagogue where the codex was kept. Mordechai Facham then smuggled it into Israel, where it can be seen on exhibit in the Israel Museum in Jerusalem. The codex reached Israel sans the first four and a half books of the Pentateuch, as well as a few books of Writings, the third section of the Bible.
