Manasseh ♂ (forget )
Manasseh was born when Joseph was between 30 and 37 years old (before the famine).
When Manasseh's grandfather Jacob was about to die, Joseph took Manasseh and Ephraim to him. Jacob then blessed the two brothers. But he blessed Ephraim as if he was the firstborn, and Manasseh as if he was the second-born. Jacob prophesied, that Manasseh will become a great people, too, but Ephraim will be greater than Manasseh.
