Contradiction with Matthew 26:4
While John 7:32 speaks of sending officers to arrest Jesus, Matthew 26:4 shows the chief priests and scribes plotting subtly to kill Him rather than a straightforward arrest.
Matthew 26:4: And consulted that they might take Jesus by subtilty, and kill [him].
Contradiction with Luke 20:19
John 7:32 depicts an active move to apprehend Jesus; however, Luke 20:19 illustrates the leaders fearing public reaction, preventing them from laying hands on Him.
Luke 20:19: And the chief priests and the scribes the same hour sought to lay hands on him; and they feared the people: for they perceived that he had spoken this parable against them.
Contradiction with John 18:6
John 7:32 shows officers intending to seize Jesus, but John 18:6 depicts them falling back instead when Jesus identifies Himself.
John 18:6: As soon then as he had said unto them, I am [he], they went backward, and fell to the ground.
Contradiction with Luke 22:53
John 7:32 involves the Pharisees sending officers to take Jesus openly, whereas Luke 22:53 notes Jesus pointing out their clandestine approach at the time of His arrest.
Luke 22:53: When I was daily with you in the temple, ye stretched forth no hands against me: but this is your hour, and the power of darkness.
