Babylonian vocalization in the context of Niqqud

The Tiberian vocalization, Tiberian pointing, or Tiberian niqqud (Hebrew: הַנִּקּוּד הַטְבֶרְיָנִי‎, romanized: hanniqquḏ haṭṭəḇeryāni) is a system of diacritics (niqqud) devised by the Masoretes of Tiberias to add to the consonantal text of the Hebrew Bible to produce the Masoretic Text. The system soon became used to vocalize other Hebrew texts as well.

Tiberian vocalization marks vowels and stress, distinguishes consonant quality and length, and serves as punctuation. While the Tiberian system was devised for Tiberian Hebrew, it has become the dominant system for vocalizing all forms of Hebrew. It has long since eclipsed the comparatively rudimentary Babylonian and Palestinian vocalization systems for writing Biblical Hebrew.

Ktav Ashuri (Hebrew: כְּתָב אַשּׁוּרִי‎, k'tav ashurí, lit. "Assyrian Writing") also (Ktav) Ashurit, is the traditional Hebrew language name of the Hebrew alphabet, used to write both Hebrew and Jewish Babylonian Aramaic. It is often referred to as (the) Square script. The names "Ashuri" (Assyrian) or "square script" are used to distinguish it from the Paleo-Hebrew script.

According to Halakha (Jewish religious law), tefillin (phylacteries) and mezuzot (door-post scripts) can only be written in Ashurit.
