Here Anne is referencing the 7th and 17th chapters of Acts, and what happens in them. In the 7th chapter Stephen is on trial where he explains the line of Abraham and how God was on their side through all of the difficulties the Israelites faced. He referenced Jacob, Joseph and Moses, and how Moses got them out of Egypt. Everyone who heard this got mad at him and stoned him to death, but at the end of his life he asked God to forgive those who killed him.

The 17th chapter of Acts follows Paul as he goes to Thessalonica, Berea, and Athens. He attempts to preach the scriptures at the Jewish synagogues in each place. In Thessalonica he was forced to leave because of rioting. In Berea he was received better, but then the Thessalonicans heard he was there they went to Berea and he was again forced to leave. Paul preached in Athens and some believed him while others did not.

Anne's use of these passages demonstrates the fact that she knows scripture, and when she was asked how she "took those sentences" is referring to how she interprets those passages. By responding the way she did, she is confirming that she interpreted the scripture without being super obvious about it. This is because she doesn't reference either Stephen or Paul in her response, but rather references Matthew 7.6 where Jesus uses the same words to say that we should not give what is holy to those who are not, because they will ruin it. So by using this verse to respond she is demonstrating she does know the bible, but she is not going to provide him an answer.
