They heard the voice contradicts 22.9 where it says that the men who were traveling with Saul did not hear the voice. In Greek it is possible for the verb “to hear” to take either the genitive case or the accusative case as its object. And so some have sought to resolve the difficulty by stating that when used with the genitive case (as here) the meaning is that the men heard the sound of the voice, but did not understand the specific words that were spoken; whereas when it is used with the accusative case (as in 22.9), the meaning is that the men both heard and understood the specific words themselves. By this reasoning the present passage would not contradict what is said in 22.9, since there it would be taken to mean that Saul’s companions did not hear (so as to understand) the words/voice. However, this conclusion is judged by most scholars as invalid; for upon examination of Luke’s usage of the verb “to hear” in Acts, it is clear that he makes no consistent distinction between “to hear” with the genitive case and “to hear” with the accusative case (see 22.1). The contradiction must remain, as must the statement in this chapter that Saul’s companions remained standing, whereas in 26.14 it is said that they all fell to the ground. Luke has simply told the same story three times (a narrative which he doubtless considers to be of great importance in the spread of the Christian message throughout the world), and we must not deny him the freedom of using differences of detail in narrating the event. It is not the responsibility of the translators to try to resolve such difficulties which he thinks may exist, but to translate faithfully what the writer has given him to translate.
