Primogeniture is the Biblical teaching that the firstborn has preeminence and authority over those that follow in the family. It is an important part of Biblical theology and can influence how certain verses are understood. Take for example, Col. 1:15 which says, "And He is the image of the invisible God, the first-born of all creation." Some cults like the Jehovah's Witnesses say that this verse means Jesus was first created. That is wrong. If the importance of "firstborn" is understood, the person would know it is not in reference to first created but to pre-eminent. We know this because the firstborn title is transferrable.
In Gen. 41:51-52, "And Joseph called the name of the first-born Manasseh: For, said he, God hath made me forget all my toil, and all my father’s house. And the name of the second called he Ephraim: For God hath made me fruitful in the land of my affliction." Jer. 31:9, " . . . for I am a father to Israel, and Ephraim is My firstborn."
Also, you can see in Gen. 25:29-34 where Esau sold his birthright of the firstborn to Jacob for a bowl of stew.
"And when Jacob had cooked stew, Esau came in from the field and he was famished; 30 and Esau said to Jacob, “Please let me have a swallow of that red stuff there, for I am famished.” Therefore his name was called Edom. 31 But Jacob said, “First sell me your birthright.” 32 And Esau said, “Behold, I am about to die; so of what use then is the birthright to me?” 33 And Jacob said, “First swear to me”; so he swore to him, and sold his birthright to Jacob. 34 Then Jacob gave Esau bread and lentil stew; and he ate and drank, and rose and went on his way. Thus Esau despised his birthright."
