仁王護國般若波羅蜜多經疏 3.648

3.648

解曰：四部弟子者，住持眾也。國王百官者，立護眾也。教依此二得住世間，不持不護即破滅故。從此第二舉喻彰過。

Explanation: "The disciples of the fourfold assembly" refers to the assembly that upholds [the Dharma]. "Kings and the hundred officials" refers to the assembly that establishes and protects [it]. The teaching relies on these two to abide in the world; if they neither uphold nor protect it, it is destroyed. Next is the second [subdivision], adducing an analogy to reveal the fault.
