See, it would be a fantastic G-d Power.
I mean things like that it would be good to add Israelite Culture.
Look I have ideas too for some Israelite GPs:
1. Waters Split- Split Water from edge to edge, and closes when your units and allied ones have passed, or as Leif Ericsson said, you click on a button to close and kill enemy units there.
2. The Twelve Plagues- Locusts: Destroy farms in a certain Area; Blood River: Any enemy Ships will be destroyed or converted to yours; Frogs: Give any ideas! ; Meteror Shower included; Death of the Major son: kills all enemy villagers when used. Etc.
Also I've some ideas for MUs.
1. Galemi or Golem: A Stone Giant who's immune to archers, medusae, and can be used as siege weapon.
2. Tread: Just as the Norse tread a tree that has live and you can control, but with fire... You know what I mean, when G-d talks to moses burning one bush.... Like the Israelite Fire Giant...
And the Army.
1. Swordsmen- Maybe chaeper and faster than any other.
2. Archers- Faster and cheaper.
3. Slingers- More powerful than Egyptian ones.
4. No Cavalry.
5. No siege weapon- Maybe Golem could be used as that.
6. No naval units.
7. Spearmen- Fastest and cheapest,but weakest.
Heros.
1. Moses, and all sucesors.
2. Abraham, Isaac and Jacob.
All with the MU banishing ability.
Buildings.
Really simple- TC, Market, Fortress, Barracks and Temples.
Favor Gathering.
Praying and Animal Sacrifice.
