I know that it is not in the game but the civ pages discribe the Korean Civ and it says that

• Jeobju: Korean Mounted Donghak Monk. Can boost his attack through the 7 saint spears ability. Can stun treasure guardians and collect treasures. If knocked down can be revived by a nearby unit. A new Jeobju can be trained in the Town Center for 300 gold.

I do not get it what does the seven saint spears that Jeobju uses...

Does he have seven skills that use the saint spear? or is it just a mistranslation of the spear of '칠성' ('Chilseong' means the seven stars <of the north>) perhaps? 

You're overthinking it. It's just the ability Kichiro has on the campaign.
