The quick answer
Who was Manasseh, son of Joseph?
Manasseh was Joseph and Asenath’s firstborn son and Ephraim’s older brother. He was born in Egypt before the famine. Jacob counted him as one of his own sons for inheritance and promised that he would become a people and be great, although he placed younger Ephraim first. The tribe of Manasseh descended from him.
Joseph’s explanation of the name
What does the name Manasseh mean?
Manasseh is the Hebrew Menasheh, commonly explained as “causing to forget.” Strong’s Hebrew entry 4519 links it with the verb for forgetting. In Genesis 41:51, Joseph says, “God has made me forget all my toil, and all my father’s house.” That is the World English Bible wording.
Later Joseph recognizes his brothers and asks about his father; he has not lost his memory of them (Genesis 42:7–8; 43:27; 45:14–15). Reading the name as relief from past hardship fits that later account, but the naming verse does not tell us exactly how Joseph felt about each family member.
People who share the name
Is Joseph’s son the same as King Manasseh?
No. Joseph’s son lived in the Genesis account. King Manasseh was Hezekiah’s son, a ruler of Judah centuries later. His fifty-five-year reign is not the lifespan of Joseph’s son.

Joseph’s firstborn in Egypt, older brother of Ephraim, and father of Machir.

Ezra 10:30, 33Why he matters
Why is Manasseh important in the Bible?
His name recalls Joseph’s hardship
Joseph names his firstborn after leaving prison and being appointed to govern Egypt.
He shares Joseph’s double inheritance
Jacob counts both brothers as sons, producing two tribal lines from Joseph.
His tribe spans the Jordan
Joshua 22:7 distinguishes the eastern and western portions of Manasseh’s inheritance.
Five moments in Genesis
Manasseh’s life from birth to later generations
Genesis records Manasseh’s birth, Jacob’s blessing, and his growing family. It gives no speech by Manasseh and no account of his death.

Born to Joseph and Asenath before the famine
Genesis 46:20
Counted among Jacob’s Egypt-born grandsons
Genesis 48:1–5

Manasseh’s family tree
Parents, brother, son, and grandson
Manasseh belongs to Joseph’s Egyptian household and becomes the head of a large family line through Machir and Gilead.
Ephraim
Jacob places Ephraim first, while promising greatness to both brothers.
Jacob & Rachel
Jacob counts both grandsons as his own sons for inheritance.
Machir
Machir becomes the leading ancestor of eastern Manassite families.
Gilead
His name becomes closely associated with the family and region east of the Jordan.
Firstborn status and younger-brother priority
Ephraim and Manasseh
Manasseh was older, but Jacob intentionally gave Ephraim the right-hand blessing. This did not remove Manasseh from the family or cancel his future. Both become tribal ancestors and receive inheritance.
Joseph’s firstborn
Joseph positions him at Jacob’s right hand in expectation of firstborn priority.
Genesis 48:13, 18The younger brother
Jacob knowingly places his right hand on Ephraim’s head.
Genesis 48:14Both are counted as Jacob’s sons
Each brother’s family receives its own tribal inheritance.
Genesis 48:5–6; Joshua 14:4Manasseh will also be great
Jacob’s prediction explicitly includes population and greatness for the older son.
Genesis 48:19The left hand still carries a real blessing
Did Manasseh lose the firstborn blessing?
Manasseh did not receive the greater position Joseph expected, but Scripture never presents him as disowned or cursed. Jacob blesses Joseph through both boys, names both in Israel’s blessing formula, and promises Manasseh greatness.
Right hand for the firstborn
Joseph takes Jacob’s hand to move it from Ephraim to Manasseh.
Genesis 48:17–18“I know, my son, I know”
Jacob is not confused by age or blindness; he deliberately chooses the order.
Genesis 48:19A people who will be great
Jacob explicitly promises descendants and greatness to Manasseh too.
Genesis 48:19Ephraim is placed first
The blessing formula names Ephraim before Manasseh and predicts wider growth.
Genesis 48:20Machir’s family and Zelophehad’s daughters
Who were Manasseh’s descendants?
Machir was Manasseh’s son, and Gilead was Machir’s son. Numbers 26:29–33 traces the family from Gilead through Hepher to Zelophehad. Zelophehad had five daughters and no sons; their request for land led to a ruling about inheritance.
Manasseh’s son
His descendants become associated with warriors and land east of the Jordan.
Genesis 50:23; Numbers 26:29Machir’s son
His family branches include several of the major Manassite clans.
Numbers 26:29–32Mahlah, Noah, Hoglah, Milcah & Tirzah
They petition for their father’s inheritance when he dies without sons.
Numbers 27:1–11Asriel and the Aramean concubine
Numbers 26:29–31 places Asriel among Gilead’s sons. In 1 Chronicles 7:14, the WEB names Asriel and Machir with Manasseh’s unnamed Aramean concubine; the KJV separates the Machir clause with a parenthesis.
Numbers 26:29–31; 1 Chronicles 7:14The difference involves both the family lists and their translation. Compare the translations of 1 Chronicles 7:14: the NIV uses “descendant” for Asriel, whereas the WEB begins with “sons.” Read the lists alongside one another rather than assuming every name belongs to the same generation.
Numbers 27 and 36 and Joshua 17:3–6 give the daughters’ story in stages: God approves their petition, a later command requires marriage within their father’s tribe to retain the tribal land, and Joshua grants their inheritance. The account includes both their right to land and the marriage restriction; it is not a general statement that daughters and sons received identical shares.
No personal lifespan is recorded
How old was Manasseh when he died?
The Bible does not state the age at death or burial place of Joseph’s son Manasseh. Genesis 50:23 mentions his son Machir and Machir’s children but gives no death notice for Manasseh. King Manasseh’s fifty-five-year reign belongs to a different person and is not an answer to this question.
One tribe, two geographic portions
Why is it called the half-tribe of Manasseh?
Manassite territory lay on both sides of the Jordan River. Families associated with Machir and Gilead received conquered land in Gilead and Bashan to the east; the remaining clans received their main allotment west of the river.
Gilead and Bashan
Moses grants land connected with the kingdoms of Sihon and Og to part of Manasseh.
Numbers 32:33, 39–42; Joshua 13:29–31Central Canaan north of Ephraim
Joshua describes the other portion and its clan inheritances.
Joshua 17:1–11The tribe is not inferior
“Half” describes the portion on one side of the river, not half membership or half a blessing.
Geography, not rankEastern warriors cross to help
They assist the other tribes before returning to their eastern inheritance.

Manasseh and Ephraim receive Jacob’s blessing
Manasseh remains blessed even though Jacob places his right hand on Ephraim. Their adoption into Jacob’s family helps explain why Joseph’s descendants are represented by two tribal names.
