Hesiod

Justice prevails over transgression when she comes to the end of the race.

He is senseless who would match himself against a stronger man; for he is deprived of victory and adds suffering to disgrace.

It is a hard thing for a man to be righteous, if the unrighteous man is to have the greater right.

Work is not a shame. Laziness is a shame.

It will not always be summer: build barns.

It is not possible either to trick or escape the mind of Zeus.

Whoever happens to give birth to mischievous children lives always with unending grief in his spirit and heart.

Do not seek evil gains; evil gains are the equivalent of disaster

But they who give straight judgements to strangers and to those of the land and do not transgress what is just, for them the city flourishes and its people prosper.

Observe due measure, for right timing is in all things the most important factor.

Never make a companion equal to a brother.

Far best is he who is himself all-wise, and he, too, good who listens to wise words; But whoso is not wise or lays to hear another's wisdom is a useless man.

Peace is a nursing mother to the land.

Long exercise, my friend, inures the mind; And what we once disliked we pleasing find.

Of themselves diseases come upon men continually by day and by night, bringing mischief to mortals silently; for wise Zeus took away speech from them. So is there no way to escape the will of Zeus

That man is best who sees the truth himself. Good too is he who listens to wise counsel. But who is neither wise himself nor willing to ponder wisdom is not worth a straw.

He's only harming himself who's bent upon harming another

Do not put your work off till to-morrow and the day after; for a sluggish worker does not fill his barn, nor one who puts off his work: industry makes work go well, but a man who puts off work is always at hand-grips with ruin.

Before the gates of excellence the high gods have placed sweat; long is the road thereto and rough and steep at first; but when the heights are reached, then there is ease, though grievously hard in the winning.

The half is greater than the whole.

Gossip and rumor are evil; easy to lift up, heavy to carry, and hard to put down again.
