Contradiction with Joshua 24:32
This verse states that Jacob bought the parcel of ground in Shechem from the sons of Hamor, contradicting Genesis 48:22 where Jacob implies he took it by force.
Joshua 24:32: And the bones of Joseph, which the children of Israel brought up out of Egypt, buried they in Shechem, in a parcel of ground which Jacob bought of the sons of Hamor the father of Shechem for an hundred pieces of silver: and it became the inheritance of the children of Joseph. [pieces...: or, lambs]
Contradiction with Genesis 33:19
This verse mentions Jacob purchasing a parcel of land in Shechem from the sons of Hamor for a hundred pieces of money, contradicting the claim in Genesis 48:22 of taking the land with his sword and bow.
Genesis 33:19: And he bought a parcel of a field, where he had spread his tent, at the hand of the children of Hamor, Shechem's father, for an hundred pieces of money. [Hamor: Gr. Emmor] [pieces...: or, lambs]
Paradox #1
Genesis 48:22 might be seen as inconsistent because Jacob mentions giving Joseph a portion of land taken from the Amorites, but the Bible doesn't clearly record Jacob fighting them to acquire it. Some people find it confusing how Jacob could give something that isn't recorded as being captured by him.
Paradox #2
Genesis 48:22 mentions Jacob giving Joseph a portion of land he took from the Amorites with his sword and bow. The contradiction or inconsistency here could be that there is no other biblical account of Jacob physically fighting or taking land in such a manner. Generally, Jacob is not depicted as a warrior in other scriptures.
