How do we know that God will judge those who persecute His messengers?

Scripture emphasizes that God is aware of the treatment His servants receive. The verses indicate that the Jews had often mistreated God's messengers, leading them to believe that their actions would go unpunished. However, our Lord makes it clear that He sees all actions and will hold people accountable for the innocent blood that has been shed. This is further supported by historical accounts of persecution and a prophetic warning of judgment that their actions would ultimately bring disaster upon themselves.
