("Jehovah is peace".) Gideon so-called his altar of thanksgiving (not sacrifice) in Ophrah, to commemorate the angel of Jehovah's salutation, "Peace be unto thee"; where rather judgment for national backslidings was to have been expected, and when he himself had feared death, as having seen the angel of Jehovah. Jehovah's assurance of "peace" confirmed His previous announcement that Gideon would conquer Midian and deliver Israel.
