Contradiction with Acts 3:13-15
Matthew 27:18 states that Jesus was delivered out of envy, while Acts 3:13-15 indicates that it was because they rejected the Holy One and desired a murderer to be granted instead.
Acts 3:13-15: The God of Abraham, and of Isaac, and of Jacob, the God of our fathers, hath glorified his Son Jesus; whom ye delivered up, and denied him in the presence of Pilate, when he was determined to let [him] go.
Contradiction with John 11:47-50
Matthew 27:18 suggests envy motivated Jesus' delivery, whereas John 11:47-50 presents it as a calculated decision for the benefit of the nation.
John 11:47-50: Then gathered the chief priests and the Pharisees a council, and said, What do we? for this man doeth many miracles.
Paradox #1
The contradiction or conflict one might see in the context of Matthew 27:18 could be related to the idea of envy leading to wrongdoing. On one hand, envy is considered a negative moral trait, yet it is shown as a powerful motivator for actions with serious consequences. The conflict lies in understanding why such a negative feeling is allowed to influence important events.
