I saw an idea mentioned on BGG called 'Moses and the Golden Calf'. I did not like the mechanics (that was fairy and dragon) but the idea would be better as the Ark in reverse. The Golden Calf deducts points from the followers it passes. However, the Golden Calf cannot occupy the tile that the Ark is currently residing upon; neither can the Golden Calf occupy the scoring area of a temple (an orthogonal cross with the temple in the middle). The Golden Calf is seen as idolatry among the Israelites as they worship the Golden Calf instead of God.
Moses and the Golden Calf is an idea that, although in the OT, predates Joshua's entering into the Promised Land, in fact, Moses was dead when Joshua entered into the Land... but the reminder of the event could be in the game.

Moving the Golden CalfThe Golden Calf is placed on the board immediately when the sixth city is completed. The player who completed that city, decides on which tile of the city he wishes to place The Golden Calf. He places
The Golden Calf on one of the completed city segments and his turn is now over.
Red chooses not to place a follower and instead moves The Golden Calf. Since The Golden Calf
passes both a red follower and a blue follower, players red and blue each lose 1 point.
Now that The Golden Calf is on the playing surface you have the option, after you have played a tile, of placing a follower, moving The Ark, moving the Golden Calf, or taking no action. If you decide to move The Golden Calf, you can move it from 1 to 5 tile spaces. You may not move it onto a tile that you have already moved across on your turn (you can not backtrack). For each follower that you pass with The Golden Calf, that player loses 1 point.
Note: If The Golden Calf starts on a tile which includes a follower, that follower does not lose 1 point when The Golden Calf begins its journey. If The Golden Calf ends on a tile with a follower, that follower loses 1 point.
