John Chrysostom, on Prov 22:20

“Behold I have described it to thee three manner of ways, in thoughts and knowledge:”

“As human beings consist of body, soul and spirit, so also Scripture consists of the body of letters, by which the ignorant man is benefited; and that is called "manual instruction." Second, it consists of soul, that is, a higher meaning, which the one who is higher in learning understands. It also consists of spirit, that is, a more sublime and spiritual contemplation which those who are perfect understand and speak.”
