13:45 But when the Jews saw the crowds, they were filled with jealousy, and they began to contradict what Paul was saying by reviling him. 13:46 Both Paul and Barnabas replied courageously, “It was necessary to speak the word of God to you first.

Acts 28:25-28

28:25 So they began to leave, unable to agree among themselves, after Paul made one last statement: “The Holy Spirit spoke rightly to your ancestors through the prophet Isaiah 28:26 when he said,

‘Go to this people and say,

“You will keep on hearing, but will never understand,

and you will keep on looking, but will never perceive.

28:27 For the heart of this people has become dull,

and their ears are hard of hearing,

and they have closed their eyes,

so that they would not see with their eyes

and hear with their ears

and understand with their heart

and turn, and I would heal them.”’

28:28 “Therefore be advised that this salvation from God has been sent to the Gentiles; they will listen!”
