When Gideon realized that it was the angel of the LORD, he exclaimed, “Alas, Sovereign LORD! I have seen the angel of the LORD face to face!”
But the LORD said to him, “Peace! Do not be afraid. You are not going to die.”
So Gideon built an altar to the LORD there and called it The LORD Is Peace. To this day it stands in Ophrah of the Abiezrites.
