פירוש על קידושין 62:13

When he would teach at his regular lecture: And whisper a matter of law to the disseminator in the name of Rav Ashi, his father - he would say to the disseminator, "This is what my father, my teacher said."

And his disseminator: When he orates [it] to the public in the name of the one that said it, he says, "This is what Rav Ashi said." And he does not say, "This is what the father and the master of the Sage said.'

When quoting a tradition in the name of his father or teacher, a sage should not say his name. This is considered disrespectful. But when the meturgeman, sort of a loudspeaker who would say the sage’s words in a very loud voice, quotes the tradition he can say the sage’s father’s or teacher’s name.
