Acts 22:8-9

22:8 I answered, ‘Who are you, Lord?’ He said to me, ‘I am Jesus the Nazarene, whom you are persecuting.’ 22:9 Those who were with me saw the light, but did not understand ¹  the voice of the one who was speaking to me.

¹ tn Grk “did not hear” (but see Acts 9:7). BDAG 38 s.v. ἀκούω 7 has “W. acc. τὸν νόμον understand the law Gal 4:21; perh. Ac 22:9; 26:14…belong here.” If the word has this sense here, then a metonymy is present, since the lack of effect is put for a failure to appreciate what was heard.
