Deuterocanon

Sirach 21:21

Ben Sira, Ecclesiasticus

19 To a senseless person education is fetters on his feet, and like manacles on his right hand. 20 A fool raises his voice when he laughs, but the wise smile quietly. 21 To the sensible person education is like a golden ornament, and like a bracelet on the right arm. 22 The foot of a fool rushes into a house, but an experienced person waits respectfully outside. 23 A boor peers into the house from the door, but a cultivated person remains outside.

Clement of Alexandria The Instructor 3.11

Paedagogus

And if it is necessary for us, while engaged in public business, or discharging other avocations in the country, and often away from our wives, to seal anything for the sake of safety, He (the Word) allows us a signet for this purpose only. Other finger-rings are to be cast off, since, according to the Scripture, instruction is a golden ornament for a wise man.
