Dhamma Verses (Dhammapada, KN 2)

19: The Chapter about One who stands by Dhamma – 235
The person to be honoured
Some learned monks, jealous of other monks having disciples
who carried out their duties for them, went to the Buddha and
asked for others to be forbidden to teach until they had
undertaken training under their tutelage; the Buddha
understood their intentions and taught them with this verse.
262-263. Na vākkaraṇamattena vaṇṇapokkharatāya vā
sādhurūpo naro hoti, issukī maccharī saṭho;
yassa cetaṁ samucchinnaṁ, mūlaghaccaṁ samūhataṁ,
sa vantadoso medhāvī sādhurūpo ti vuccati.
Not by eloquence only, or
by a beautiful complexion,
is a person honourable,
if jealous, selfish, deceitful;
the one in whom this is cut-off,
destroyed at the root and dug up,
that sage who has thrown out hatred
is said to be honourable.
