Contradiction with Deuteronomy 32:4
While Isaiah 5:3 invites judgment on the vineyard, Deuteronomy 32:4 proclaims the perfection and justice of God's work, not recognizing any failure in it.
Deuteronomy 32:4: [He is] the Rock, his work [is] perfect: for all his ways [are] judgment: a God of truth and without iniquity, just and right [is] he.
Contradiction with Isaiah 5:4
Right after Isaiah 5:3, this verse questions what more could have been done for the vineyard, contradicting the idea that any lack is due to God's actions.
Isaiah 5:4: What could have been done more to my vineyard, that I have not done in it? wherefore, when I looked that it should bring forth grapes, brought it forth wild grapes?
