Revelation 13:9

If any man hath an ear, let him hear.

The contemporary equivalent of this is, Now hear this! It occurs in each of the seven letters (Revelation 2:7,11,17; Revelation 3:6,13,22) and recalls the familiar expression of Jesus, "He who has ears to hear, let him hear" (Matthew 11:15; Mark 4:9). It alerts the reader to the importance of what follows.[62]

Morris also thought the alert here "regards what follows in stead of what precedes.[63] This makes verses Revelation 13:9,10 a solemn warning "against any effort on the part of the church to return evil for evil."[64]
