Contradiction with Job 4:7
Luke 13:1 suggests a causal relationship between suffering and sin, while Job 4:7 argues against that correlation by asserting the innocence of those who suffer.
Job 4:7: Remember, I pray thee, who [ever] perished, being innocent? or where were the righteous cut off?
Contradiction with John 9:2-3
Luke 13:1 presents an implicit suggestion of sin behind suffering, while John 9:2-3 explicitly refutes this by stating neither the man nor his parents sinned to cause his blindness.
John 9:2-3: And his disciples asked him, saying, Master, who did sin, this man, or his parents, that he was born blind?
Contradiction with Ecclesiastes 9:2-3
Luke 13:1 implies a discernible moral reason for tragic events, whereas Ecclesiastes 9:2-3 suggests that events happen to everyone regardless of morality.
Ecclesiastes 9:2-3: All [things come] alike to all: [there is] one event to the righteous, and to the wicked; to the good and to the clean, and to the unclean; to him that sacrificeth, and to him that sacrificeth not: as [is] the good, so [is] the sinner; [and] he that sweareth, as [he] that feareth an oath.
Contradiction with Psalm 73:3-5
Luke 13:1 might hint at justice in misfortune but Psalm 73:3-5 depicts the wicked prospering without suffering.
Psalm 73:3-5: For I was envious at the foolish, [when] I saw the prosperity of the wicked.
Contradiction with Matthew 5:45
Luke 13:1 implies that certain people suffer due to sin, but Matthew 5:45 states that God causes the sun to rise on the evil and the good, implying impartiality in events.
Matthew 5:45: That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust.
