Many Jews used Mishnaic Hebrew well into the Middle Ages and up to the present day as both a liturgical and literary language, and they also employed it as for commerce between disparate diasporic communities.
This family of languages also has the distinction of being the first historically attested group of languages to use an alphabet, derived from the Proto-Canaanite alphabet, to record their writings, as opposed to the far earlier Cuneiform logographic/syllabic writing of the region, which originated in Mesopotamia and was used to record Sumerian, Akkadian, Eblaite, Elamite, Hurrian and Hittite.
They are heavily attested in Canaanite inscriptions throughout the Levant, Mesopotamia, Anatolia and the Eastern Mediterranean, and after the founding of Carthage by Phoenician colonists, in coastal regions of North Africa and Iberian Peninsula also.
All of the other Canaanite languages seem to have become extinct by the early first millennium AD except Punic, which survived into late antiquity (or possibly even longer).
Slightly varying forms of Hebrew preserved from the first millennium BC until modern times include: The Phoenician and Punic expansion spread the Phoenician language and the Punic variety spoken in the antique-era colonies in Western Mediterranean for a time, but there too it died out, although it seems to have survived longer than in Phoenicia itself.
