Gideon's Divine Encounter: The Naming of Jehovah Shalom
After meeting face to face with the Angel of the Lord, Gideon called God "Jehovah Shalom." This is derived from the account of the encounter, which states:"And Gideon saw that it was the Angel of the Lord, and Gideon said, 'Woe is me, my Lord! For I have seen the Angel of the Lord face to face.' The Lord said to him, 'Peace be to you; do not be afraid, you shall not die.' And there Gideon built an altar to the Lord and called it Jehovah Shalom. It remains in Ophrah of the Abiezrites to this day."
