Jest not with the eye, or religion.

John has been to school to learn to be a fool.

Justifying a fault doubles it.

Keep a stiff upper lip.

Kindred without friends, friends without power, power without will, will without effect, effect without profit, profit without virtue, is not worth a rush.

Kings have long hands.

Laws have wax noses.

Lawyers' houses are built of fools' heads.

Lawyers' houses are built on the heads of fools.

Laziness is often mistaken for patience.

Learning is there for every man.

Leave the minster where it is.

Leave well alone.

Let every one mind his own business, and the cows will be well tended.

Let him who feels he has a dirty nose wipe it.

Let him who is cold blow the fire.

Let not your shirt know your way of thinking.

Liars need good memories.

Life is half spent before one knows what life is.

Light burdens borne far become heavy.

Light is bad for sore eyes.

Like box-makers, more noise than work.

Like breeds like.

Like saint like incense.
