[267] One who is fully ordained (upasampanna), having heard it from one fully ordained, carries malicious tale-bearing (pesuñña) to one fully ordained, saying: "The bhikkhu named so-and-so says of you: 'a leper, one afflicted with boils, one afflicted with eczema, one afflicted with consumption, an epileptic'" — for each utterance, there is an offence of pācittiya.
