說無垢稱經疏 3.43

3.43

贊曰：自下第三為尊誘下權。室富、眾望權高，稱為長者，故說勝法勸厭欲塵。齒下家貧、懷道自逸，名為居士。財食既多不足故，能斷其貪著。

Commentary: Next is the third [section], the skillful means of an exalted one guiding inferiors. One possessing vast wealth, great prestige, and high authority is called an "elder" (śreṣṭhin); hence he expounded the superior Dharma to exhort them to become weary of sensory desires. Those of lower age, humble families, but embracing the Way in leisurely self-contentment are called "householders" (gṛhapati). Since wealth and food were often insufficient for them, he was able to sever their greed and attachment.
