 # Have your hearts become so dull?
 
-"Hearts" here is a metonym for "thoughts and intentions." AT: "Your thinking has become so dull!" and [[rc://en/ta/man/translate/figs-rquestion]]) (See: [[rc://en/ta/man/translate/figs-metonymy]])
+Here "hearts" is a metonym for a person's mind. The phrase "hearts become so dull" is a metaphor for not being able or willing to understand something. Jesus uses a question to scold the disciples. This can be written as a statement. AT: "Your thinking has become so dull!" or "You are so slow to understand what I mean!" (See: [[rc://en/ta/man/translate/figs-metonymy]] and [[rc://en/ta/man/translate/figs-metaphor]] and [[rc://en/ta/man/translate/figs-rquestion]])
