Contradiction with Ezekiel 22:29
Mark 12:1 introduces a parable with an act of care by planting a vineyard, yet Ezekiel 22:29 shows a context of violence and oppression in contrast to the vineyard's initial peaceful establishment.
Ezekiel 22:29: The people of the land have used oppression, and exercised robbery, and have vexed the poor and needy: yea, they have oppressed the stranger wrongfully. [oppression: or, deceit] [wrongfully: Heb. without right]
Contradiction with Luke 12:19
Mark 12:1 talks about diligence in cultivating a vineyard, while Luke 12:19 describes a person seeking ease and rest, contradicting the idea of hard work.
Luke 12:19: And I will say to my soul, Soul, thou hast much goods laid up for many years; take thine ease, eat, drink, [and] be merry.
