Kūṭadantasutta

Suttapiṭaka · Dīghanikāya · Sīlakkhandhavagga · Vol. 9 · Section 216

[216] There will come to your sacrifice, sir, both those who speak harshly and those who refrain from harsh speech. As to those there who speak harshly, the outcome of that is theirs alone; but as to those there who refrain from harsh speech, it is for their sake that the good sir should sacrifice, relinquish, rejoice, and make his inner heart confident.
