Contradiction with Isaiah 3:14
While Isaiah 5:7 speaks of God judging His vineyard for producing bad fruit, Isaiah 3:14 suggests that exploitation by leaders is the cause of devastation, placing blame on leadership rather than the community as a whole.
Isaiah 3:14: The LORD will enter into judgment with the ancients of his people, and the princes thereof: for ye have eaten up the vineyard; the spoil of the poor [is] in your houses. [eaten: or, burnt]
Contradiction with Jeremiah 12:10
Isaiah 5:7 blames the vineyard (Israel) for yielding wild grapes, while Jeremiah 12:10 attributes the vineyard's destruction to external forces, the unfaithful shepherds, thereby shifting the responsibility away from the vineyard itself.
Jeremiah 12:10: Many pastors have destroyed my vineyard, they have trodden my portion under foot, they have made my pleasant portion a desolate wilderness. [pleasant...: Heb. portion of desire]
Contradiction with Matthew 7:16
Isaiah 5:7 implies that the vineyard is expected to produce good fruit but yields bad; Matthew 7:16 contradicts this by asserting that good trees can only produce good fruit and bad trees only bad fruit, conflicting with the notion of transformation to unexpected results.
Matthew 7:16: Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
Contradiction with John 15:5
In Isaiah 5:7, the responsibility for the bad fruit lies with the vineyard (Israel); John 15:5 emphasizes that bearing good fruit is dependent on the vine's connection to Christ, suggesting it's less about the vine's inherent qualities and more about its spiritual connection.
John 15:5: I am the vine, ye [are] the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing. [without me: or, severed from me]
