瑜伽師地論略纂 3.144

3.144

麁惡語中，「先首」者，凡所說法，說趣涅槃最第一故。由此語故，以為先首，當趣涅槃。以相續故，名無盡。以廣大故，名無邊。　「即此最後，又有三種」等者，謂前三中最後，說法語中，前十二句中攝先首、美妙等八句，即諸經中說，佛說法有八語具。由持戒語，令他歡喜，具八語具。此八之中，復分三故。此別諸句，合十九句：初十二句合為三類，次四說有為行三世語，後三重攝前語。由辨諸句皆有曲結，故無略義。

In harsh speech: "foremost" means that of all Dharma preached, preaching that leads towards nirvāṇa is the supreme. Because of such speech, it is taken as foremost and one will proceed towards nirvāṇa. Because it is continuous, it is called "inexhaustible." Because it is vast, it is called "boundless." "Regarding this last one, there are again three kinds," etc.: this refers to the last among the previous three, speech preaching the Dharma; within the previous twelve phrases, it subsumes eight phrases such as "foremost" and "beautiful," which are the eight vocal endowments of the Buddha's preaching spoken of in the sutras. Through speech of upholding precepts, one causes others to rejoice, possessing the eight vocal endowments. Within these eight, they are further divided into three. These distinct phrases total nineteen phrases: the first twelve phrases are grouped into three categories, the next four speak of language regarding the three times of conditioned activities, and the final three re-subsume the preceding speech. Since the analysis of all phrases already includes indirect conclusions, there is no summarized meaning.
