501 B

knew their thoughts

Jesus knew what they were thinking either supernaturally or because he could see them talking to each other.

Why are you thinking evil in your hearts?

Jesus used this question to rebuke the scribes. Here "hearts" refers to their minds or their thoughts. Alternate translation: "Do not think evil thoughts." (See: rc://en/ta/man/translate/figs-rquestion and rc://en/ta/man/translate/figs-metonymy)

evil

This is moral evil or wickedness, not simply error in fact.
