Santhavagga

Suttapiṭaka · Khuddakanikāya · Jātaka (1) · Vol. 27 · Section 171

[171] One should not form intimacy with a vile man; a noble one, knowing the good, should form none with an ignoble man; for even after dwelling together a long time, he does evil, as the elephant did to Indasamānagotta.
