A kindly turn of speech multiplies a man's friends,
and a courteous way of speaking invites many a friendly reply.
Let your acquaintances be many,
but your advisors one in a thousand.
If you want to make a friend, take him on trial,
and be in no hurry to trust him;
for one kind of friend is only so when it suits him
but will not stand by you in your day of trouble.
Another kind of friend will fall out with you
and to your dismay will make your quarrel public,
and a third kind of friend will share your table,
but not stand by you in your day of trouble:
when you are doing well he will be your second self,
ordering your servants about;
but if ever you are brought low he will turn against you
and will hide himself from you.
Keep well clear of your enemies,
and be wary of your friends.
A faithful friend is a sure shelter,
whoever finds one has found a rare treasure.
A faithful friend is something beyond price,
there is no measuring his worth.
A faithful friend is the elixir of life,
and those who fear the Lord will find one.
Whoever fears the Lord makes true friends,
for as a man is, so is his friend.
Ecclesiasticus 6:5-17 Jerusalem Bible
Prick an eye and you will draw a tear,
prick a heart and you will bring its feelings to light.
Throw stones at birds and you scare them away,
revile a friend and you break up friendship.
If you have drawn your sword on a friend,
do not despair; there is a way back.
If you have opened your mouth against your friend,
do not worry; there is hope for reconciliation;
but insult, arrogance, betrayal of secrets, and the stab in the back—
in these cases, any friend will run away.
Ecclesiasticus 22:19-22 Jerusalem Bible
