The Bible itself mentions no other people of the name, except the original one; however, it became a very common name among Jews in Hellenistic times and remains such up to the present.

The name Judah can refer to:

• Judah (Bible), one of the sons of the Biblical patriarch Jacob (Israel)

All later individuals, groups and places of this name are directly or indirectly derived from this Judah.

Upholders of the term describe it a being an ancient, Biblical geographical terms. That is true to the extent that "Judea" and "Samaria" are - each one separately - ancient names, used respectively by Jews and by Samaritans who lived these respective areas more than 1,000 years before the arrival of the Islamic armies under the Caliph Omar ibn al-Khattāb. However, there had never been until the 20th Century a single political or administrative unit called "Judea and Samaria"; in all previous periods when these names were used at all, they were treated as two very distinct and separate units, especially since in Biblical times these were two separate kingdoms which on numerous occasions went to war with each other, and later on Jews and Samarians were each other's staunch foes throughout the Hellenistic and Roman periods. "Judea and Samaria," as describing a single area is a strictly modern term, having to mainly with post-1967 Israeli politics.
