Dhana Sutta AN 5.47

Here, a noble disciple has learned much, remembers what he has learned, and accumulates what he has learned. Those teachings that are good in the beginning, good in the middle, and good in the end, with the right meaning and phrasing, which proclaim the perfectly complete and pure spiritual life—such teachings as these he has learned much of, retained in mind, recited verbally, mentally investigated, and penetrated well by view.
