Atos 28:24-27

Luke recorded for the third and last time what had become the Jews’ characteristic response to hearing the gospel (Acts 28:24; Acts 13:46; Acts 18:6; cf. Romans 11:7-10). Paul’s parting word was a quotation from Isaiah 6:9-10 in which God told the prophet that his Jewish hearers would not believe God’s message through him (cf. Matthew 13:14-15; Mark 4:12; Luke 8:10; John 12:40-41). Paul saw that this word to Isaiah was as applicable in his own day as it had been in Isaiah’s. He also regarded it as inspired by the Holy Spirit.

"In every instance in Acts where a scriptural quote is introduced by a reference to the Spirit, the Spirit is described as having spoken (cf. 1.16; 4.25). In this manner the written Word is shown to be a dynamic, ’living’ Word." [Note: Polhill, p. 543.]

"Note how the failure to respond to the message of the gospel is seen as a failure to turn." [Note: The NET Bible note on Acts 28:27.]
