The Arab Midianites are God and Israel’s enemies, because they conspired with the Moabites to curse Israel. Additionally, the Arab Midianites are God and the Israelites’ enemies, because Midianite and Moabite women conspired to seduce Israelite men for the purpose of getting them to fall into idol worship, primarily the worship of their local deity, Baal of Peor. Now Baal was a major god of the many gods in the Canaanite pantheon, and while God did not tolerate His chosen people’s idolatry, because to do so would mean God was going against His own Laws, God loathed Baal.
In the Holy Bible, when God called a person or a city’s name twice, each occasion immediately was elevated to one of great biblical importance to that person or the city involved. Furthermore, this biblical importance also affects those of us who have come to Christ by Grace through Faith. Indeed, whenever God is using the double salutation, it is because He wants to get our attention, because He has something vitally important to say to us.
