You enver know till you have tried

You may know by a handful the whole sack

You may know the lion by his claw

You may know the fox by his tail

You never know your luck

You never know what you can do until you try

You cannot know the wine by the barrel

Who has never tasted bitter, knows not what is sweet

Who knows most, speaks least

Thou clearly knowest when to speak, and when to keep silent

What three people know, the whole world knows

What we first learn, we best know [can]

What you don’t know won’t hurt you

We never know the value of water till the well is dry

Wealth is best known by want

We know not what a day may bring forth

We know not what is good until we have lost it

War is sweet to them that know it not

Too much knowledge makes the head bald

To know what’s what

To know everything is to know nothing

To know on which side one’s bread is buttered

The worth of a thing is best known by the want of it

The workman is known by his work

The wolf knows what the ill beast thinks

The rich knows not who is his friend

The frog in the well knows nothing of the great ocean

The fox knows much, but more he that catcheth him

The devil knows many things because he is old

The cow doesn’t know what her tail is worth until she lost it

The bird is known by his note, the man by his words

Tell nothing to thy friend that thine enemy may not know

Tell not all you know, all you have, or all you can do

More knows the fool in his own house than the wise man in another’s

Men know where they were born, not where they shall die
