Fools for luck.

Fools must not be set on eggs.

Fools refuse favours.

Fools rush in where angels fear to tread.

For love the wolf eats the sheep.

For the upright there are no laws.

Forbidden fruit is sweet.

"Force me, and I shall commit no sin," said the girl.

Fore-talk spares after-talk.

Forgive and forget.

Forgive thyself nothing and others much.

Forgiven is not forgotten.

Fortune and misfortune are neighbors.

Fortune and misfortune are two buckets in a well.

Fortune and women are partial to fools.

Fortune give many too much, but no one enough.

Fortune gives her hand to a bold man.

Fortune is like women: loves youth and is fickle.

Free man, free goods.

Full vessels give the least sound.

Funeral sermon, lying sermon.

Gifts are according to the giver.
