What does "heard" mean in "I allow fish and meat that is pure in three respects: One has not seen, heard, or suspected..."

In Vinaya, there is this rule (copied from Buddhist Monastic Code II ): > "One should not knowingly consume meat killed on purpose (for a > bhikkhu). Whoever should consume it: an offense of wrong doing. I > allow fish and meat that is pure in three respects: One has not seen, > heard, or suspected (that it was killed on purpose for a bhikkhu)." — > Mv.VI.31.14 How should we interpret "heard"? I can think of some possibilities: 1. Heard from someone that it was killed for me, i.e., someone told me that it was killed for me. 1. Heard the sound of killing, e.g. sound of the animal or action of killing 1. Both of the above.
