Jerome,
Against Rufinus 3.42 (tr. John N. Hritzu):
You
shall hear nothing more on this subject except a proverb borrowed from the streets: 'When you say what you want to say,
you shall hear what you do not want to hear.'
nihilque super hoc amplius audies nisi illud de trivio: cum dixeris quod vis, audies quod non vis.
Cf. Terence,
Andria 920 (tr. John Sargeaunt):
If he persists in saying
just what he likes, he shall hear what he won't
like.
si mihi perget quae volt dicere, ea quae non volt audiet.
