Judges 6:11, 24, 34

The angel of the LORD came and sat down under the oak in Ophrah that belonged to Joash the Abiezrite, where his son Gideon was threshing wheat in a winepress to keep it from the Midianites.

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.

Then the Spirit of the LORD came on Gideon, and he blew a trumpet, summoning the Abiezrites to follow him.
