Ferr teiched tairisem.

Ferr teiched tairisem.

(better * fleeing * (than) remaining)

It's better to flee than to stay.

This three word maxim from "Bríathra Flainn Fína maic Ossu" is fleshed out somewhat in the modern version "Is fearr rith maith ná drochsheasamh." (A good run is better than a bad stand. Discretion is the better part of valor.)
