Some scholars think it was common in those days to raise a hand toward the king in order to greet him. Other scholars think Paul stretched out his hand toward the king because it indicated he was about to make a speech.
When Paul said he was happy, he meant he felt fortunate or blessed to make his case before King Agrippa. King Agrippa was also a Roman and he knew Roman laws.
Some scholars think the fathers about which Paul spoke were Abraham, Isaac, and Jacob. Other scholars think Paul was speaking about other ancestors of Israel.
God promised many things to these fathers. God promised the messiah, resurrection from the dead, the kingdom of God, and eternal life with God the Father.
Scholars think that when Jesus said, “It is hard for you to kick a goad” he used a metaphor. In ancient times, people used a goad to make an ox move. If an ox kicked against the stick, this caused more discomfort for the ox. Scholars think Jesus said this to Paul in order to tell Paul that he was resisting God. That is, when Paul wanted to persecute Christians, this fought against God. It was not what God wanted Paul to do.
Paul was able to open people’s eyes. This is a metaphor. God gave Paul the ability to teach the Gentiles about sin. Before Paul taught them, the Gentiles did not know they sinned. They now knew they sinned.
When Paul wrote about the small and the great, he was speaking about all people. The small included poor and servants. The great included rich people and free people, including King Agrippa.
When Paul said, “this has not been done in a corner” he used a metaphor. He meant that all the events that were fulfilled God’s promises and people could see these promises being fulfilled. People saw Jesus resurrected. Paul also said that all these events were prophesied by Moses and the ancient prophets of Israel.
Paul wanted people to be like him, but without prison chains. Paul prayed that Agrippa would believe Jesus as Paul believed Jesus. However, Paul did not wish Agrippa to be imprisoned. Paul was imprisoned, but he did not do anything wrong.
Scholars think that both Agrippa and Festus had heard everything they wanted to hear from Paul. When they stood up, this meant that their meeting had ended.
