The Long Āgama Sūtra 22.43

22.43

佛言：「善哉！善哉！如汝所說，有戒則有慧，有慧則有戒；戒能淨慧，慧能淨戒。種德！如人洗手，左右相須，左能淨右，右能淨左。此亦如是，有慧則有戒，有戒則有慧，戒能淨慧，慧能淨戒。婆羅門！戒、慧具者，我說名比丘。」

The Buddha said, “Good, good! As you’ve said, having precepts is having wisdom, and having wisdom is having precepts. Precepts purify wisdom, and wisdom purifies precepts. Śroṇatāṇḍya, it’s like when someone washes their hands: The right and left hand need each other. The left hand washes the right hand, and the right hand washes the left hand. These things are likewise. Having wisdom is having precepts, and having precepts is having wisdom. Precepts purify wisdom, and wisdom purifies precepts. Priest, I say someone endowed with precepts and wisdom is called a monk.”
