Who has a fair wife needs more than two eyes

Three may keep a secret, if two of them are dead

Two [many] hands [wits] are better than one

Two blacks do not make a white

Two dogs over one bone seldom agree

Two dogs strive for a bone, and a third runs away with it

Two heads are better than one

Two in distress makes sorrow less

Two is company and three is a crowd

Two shoes make a pair

Two of a trade seldom agree

Two wrongs do not make a right

Two to one is odd’s

Two’s company, three’s none

To kill two flies with one flap

To kill two birds at one stone

To kill two birds with one stone

There are two sides to every question

Put two pennies in a purse and they will dray together

Nature has given us two ears, two eyes, and but one tongue; to the end we should hear and see more than we speak

Not even Hercule could contend against two

No secret but between two

No man can serve two masters

One to-day is worth two to-morrow

To stop two gaps with one bush

One good forewit, is worth two afterwits

When one will not, two cannot quarrel

One eye has more faith than two ears

One day of pleasure is worth two of sorrow

He who wants to know himself should offend two or three of his neighbours

If two men ride on a horse, one must sit behind

If you chase two rabbits, you will not catch either  one

If you run after two hares, you will catch neither

A secret between more than two is no secret

A pound in the purse is worth two in the book
