Thematic Bible: Proclaiming war

And Jehovah said to Moses, Write this, a memorial in a book, and set it in the ears of Joshua, that I will utterly put out the remembrance of Amalek from under heavens. And Moses built an altar, and called the name of it Jehovah My Banner. And he said, A hand is on the throne of Jehovah; war is to Jehovah with Amalek from generation to generation.

And Jehovah spoke to Moses saying, Avenge the sons of Israel from the Midianites. Afterward you shall be gathered to your people.
