Hadoram is a biblical figure mentioned as one of Joktan's sons and thus a descendant of Shem, Noah's son. He is part of the table of nations in Genesis and 1 Chronicles, representing one of the Arab tribes that settled in the southern part of the Arabian Peninsula. The name Hadoram also appears in other contexts in the Bible, notably as an official under King Rehoboam.
Joktan's sons, including Hadoram, settled in the mountainous regions to the east, from Mesha toward Sephar. This describes the geographical spread of these tribes.
Hadoram is mentioned again in the genealogy in 1 Chronicles as part of Shem's descendants through Eber and Joktan, confirming his place in Israel's historical tradition.
Through his father Joktan and grandfather Eber, Hadoram belongs to the Semitic branch of Noah's descendants, which is an important part of the Bible's family history.
Eber had two sons: Peleg, through whom Abraham's line continues, and Joktan, who became the father of Hadoram and his brothers. This shows the branching out of the Semitic peoples.
