Contradiction with Genesis 33:19
This verse states that Jacob bought the field from the children of Hamor, contradicting the concept that Joseph's bones were buried in a place exclusively linked to property purchased by the Israelites rather than their ancestors.
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]
Contradiction with Acts 7:16
This verse suggests that the bones were carried over to Sychem and laid in a grave bought by Abraham, contradicting Joshua 24:32 which states Jacob bought the land, not Abraham.
Acts 7:16: And were carried over into Sychem, and laid in the sepulchre that Abraham bought for a sum of money of the sons of Emmor [the father] of Sychem.
