Judges 6:11, 24, 34

Now the Angel of the LORD came and sat under the terebinth tree which was in Ophrah, which belonged to Joash the Abiezrite, while his son Gideon threshed wheat in the winepress, in order to hide it from the Midianites.

So Gideon built an altar there to the LORD, and called it The-LORD-Is-Peace. To this day it is still in Ophrah of the Abiezrites.

But the Spirit of the LORD came upon Gideon; then he blew the trumpet, and the Abiezrites gathered behind him.
