What Prophecy Did Jacob Give Regarding Joseph’s Sons?
Before Jacob died, he performed a significant and prophetic act: he adopted Joseph’s two sons, Ephraim and Manasseh, and blessed them. This moment became one of the most important turning points in Israel’s tribal history. Jacob’s prophecy over Joseph’s sons did more than give them an inheritance—it placed them at the center of God’s unfolding plan for His people.
1. Jacob Adopted Ephraim and Manasseh as His Own
Jacob began by declaring:
“Your two sons… are mine; Ephraim and Manasseh shall be mine, as Reuben and Simeon are” (Genesis 48:5).
This meant:
-
Ephraim and Manasseh each received full tribal status.
-
Joseph effectively received the double portion reserved for the firstborn.
-
Ephraim and Manasseh replaced Reuben and Simeon as the first two in inheritance ranking.
This adoption was itself prophetic—Joseph, not Reuben, became the true firstborn heir.
2. Jacob Crossed His Hands: Ephraim Receives the Greater Blessing
When Jacob blessed the boys, he crossed his arms:
-
His right hand (symbol of greater authority) rested on Ephraim, the younger.
-
His left hand rested on Manasseh, the older.
Joseph protested, but Jacob refused to change his hands, saying:
“I know, my son… Manasseh shall become a people, and he also shall be great;
but truly his younger brother shall be greater than he.”
—Genesis 48:19
This gesture symbolized God’s sovereign choice, which often favors the unlikely:
-
Isaac over Ishmael
-
Jacob over Esau
-
Judah over older brothers
-
David, the youngest, over his brothers
Jacob’s crossed hands revealed that God’s plan does not depend on human order or expectation.
3. Prophecy Over Manasseh: He Will Become a Great People
Jacob prophesied that Manasseh would grow into:
-
A significant tribe
-
Strong and numerous
-
A people of influence
Manasseh eventually became:
-
One of Israel’s largest tribes
-
Holder of a double land portion (half east of the Jordan, half in Canaan)
-
A tribe with strong warriors (e.g., Gideon came from Manasseh)
The prophecy ensured Manasseh would be great—just not the greatest.
4. Prophecy Over Ephraim: A Multitude of Nations
Jacob declared:
“His descendants shall become a multitude of nations.”
—Genesis 48:19
This prophecy meant:
-
Ephraim would surpass his brother in size and influence
-
He would become the dominant northern tribe
-
His descendants would spread widely and become many nations (interpreted as peoples, clans, or groups)
In Israel’s history, Ephraim became:
-
The largest and most powerful tribe in northern Israel
-
The tribe often representing the entire northern kingdom
-
The source of major leaders (e.g., Joshua came from Ephraim)
When the kingdom divided, the prophets often used “Ephraim” as shorthand for all 10 northern tribes—fulfilling Jacob’s words.
5. Jacob Gave Joseph a Special Blessing Through His Sons
Jacob declared over Joseph:
“The God who has been my shepherd… bless the lads.”
—Genesis 48:15–16
This blessing included:
-
Protection
-
Fruitfulness
-
Multiplication
-
Continuity of God’s covenant through Joseph’s line
It affirmed that Joseph’s faithfulness would be honored across generations.
6. Jacob Gave Joseph an Extra Portion in the Land
Jacob said:
“I give you one portion more than your brothers” (Genesis 48:22).
The Hebrew word shekem means:
-
“Portion”
-
Or literally “Shechem,” the region Joseph would inherit
This was symbolic:
-
Joseph’s descendants received two tribal territories (Ephraim and Manasseh)
-
Fulfilling the firstborn double portion over Joseph
-
Establishing Joseph’s line as the most land-rich inheritance in Israel
7. Jacob Established a Blessing Tradition in Israel
Jacob said:
“In you shall Israel bless, saying,
‘God make you like Ephraim and like Manasseh.’”
—Genesis 48:20
This became a traditional blessing for Jewish families, spoken over children to this day. The reason:
-
Ephraim and Manasseh were the first brothers in Scripture who lived in harmony, not rivalry
-
They represented unity, fruitfulness, and God’s grace
8. The Prophecy Reveals God’s Sovereign Choice
The blessing on Joseph’s sons teaches powerful spiritual truths:
-
God chooses according to His purpose, not human expectation
-
God honors obedience and faithfulness across generations
-
God elevates the humble
-
God fulfills His promises through unexpected people
Through Jacob’s prophecy, Ephraim and Manasseh became central to God’s plan for Israel’s future.

Gave his descendants double inheritance
