But al that he myghte of his freendes hente,
On bookes and on lernynge he it spente,
And bisily gan for the soules preye
Of hem that yaf hym wherwith to scoleye.

– Geoffrey Chaucer

The Canterbury Tales, General Prologue. The poor Clerk spends all the money he can get from his friends on books and learning. And he dilligently prays for the souls of those who lend him money for books and lessons.
