St. Theophylact: The Lord shows us that we ought not to answer . . .
“The Lord shows us that we ought not to answer those who ask a question with malicious intent (cf. Mt. 21:23-27). For He Himself did not reply to those Jews who questioned Him with cunning, although He was not at a loss for an answer.”
