The prosperous fortunes, and the haughty wealth
Of an unrighteous man, we never ought
To deem establish’d on a solid base,
Or that the children of th’ unjust can prosper:
For Time, who from no Father springs, applies
His levell’d line, and shews man’s foul misdeeds.
 
[οὐδέποτ᾽ εὐτυχίαν κακοῦ ἀνδρὸς ὑπέρφρονά τ᾽ ὄλβον
βέβαιον εἰκάσαι χρεών,
οὐδ᾽ ἀδίκων γενεάν” ὁ γὰρ οὐδενὸς ἐχφὺς
χρόνος δικαίους ἐπάγων κανόνας
δείκνυσιν ἀνθρώπων καχότητας ἐμοί.]

(Source (Greek)). Alternate translations:

Think not that the prosperity and riches of the wicked can endure, nor yet the generation of the bad; for Time, sprung from eternity, having a just rule in his hand, shows the wickedness of men.
[Source (1878)]

One ought never to imagine the success of a bad man, and his proud wealth, as secure, nor the lineage of unjust men; for time, which was born from nothing, adduces standards which are just and shows the wickedness of men in spite of all.
[tr. Collard, Hargreaves, Cropp (1995)]

It must not be believed
that the wicked thrive securely
though puffed-up-proud in their prosperity
nor the long line of injustices go on and on
uninterrupted -- Self-generating Time
(slowly -- slowly) lays
the yardstick of justice --
into the open (at least) brings
all iniquities of men.
For all that. For all that.
[tr. Stevens (2012)]
