The Long Āgama Sūtra 11.4

11.4

爾時，世尊告諸比丘：「我與汝等說微妙法，上中下言，皆悉真正，義味清淨，梵行具足，謂一增法也。汝等諦聽！善思念之！當為汝說。」

It was then that the Bhagavān addressed the monks, “I will give you a discourse on the sublime teaching in which all the words in the beginning, middle, and end are true, the content and expression are pure, and the religious life is perfected. It’s called the teaching that increases one by one. All of you, listen closely and consider it well! I will teach it for you.”
