Contradiction with Exodus 20:12
This verse commands honoring one's parents, while Genesis 50:12 merely describes Joseph's brothers obeying their father's command, potentially without a display of honor.
Exodus 20:12: Honour thy father and thy mother: that thy days may be long upon the land which the LORD thy God giveth thee.
Contradiction with Matthew 8:22
Instructs to "let the dead bury their dead," contrasting with Joseph's brothers actively burying their father as stated in Genesis 50:12.
Matthew 8:22: But Jesus said unto him, Follow me; and let the dead bury their dead.
Contradiction with Luke 9:60
Similar to Matthew 8:22, it advises to preach the kingdom of God rather than focusing on burial, opposing the act of burial in Genesis 50:12.
Luke 9:60: Jesus said unto him, Let the dead bury their dead: but go thou and preach the kingdom of God.
