Self Defense in The Bible - Michael Heiser
"Dr. Michael Heiser goes over the biblical context for appropriate uses of self defense. What's an appropriate Christian response?" from video introduction.

In his zeal to defend the Lord, Peter was standing in the way of God’s will. Jesus had told His disciples multiple times that He must be arrested, put on trial, and die (e.g., Matthew 17:22–23). In other words, Peter acted unwisely in that situation. We must have wisdom regarding when to fight and when not to.." from the article: What does the Bible say about self-defense?
