Contradiction with Matthew 13:16-17
These verses indicate that the disciples are blessed for seeing and hearing things that many have desired to see and hear, suggesting that some people do have the ability to perceive and understand, which contradicts the idea in Deuteronomy 29:3 that the people lacked the heart, eyes, and ears to perceive the great deeds performed by God.
Matthew 13:16-17: But blessed [are] your eyes, for they see: and your ears, for they hear.
