Some friendships do not last, but some friends are more loyal than brothers.
~ Proverbs 18:24

Forsake not an old friend; for the new is not comparable to him: a new friend is as new wine; when it is old, thou shall drink it with pleasure.
~ Sirach 9:10

An honest answer is the sign of true friendship.
~ Proverbs 24:26

A friend means well, even when he hurts you. But when an enemy puts his hand round your shoulder - watch out!
~ Proverbs 27:6

Two are better than one; because they have a good reward for their labour. For if they fall, the one will lift up his fellow: but woe to him that is alone when he falleth; for he hath not another to help him up.
~ Bible: Ecclesiastes

My friends are my estate. Forgive me then the avarice to hoard them. They tell me those who were poor early have different views of gold. I don't know how that is. God is not so wary as we, else He would give us no friends, lest we forget Him.
~ Emily Dickinson

The greatest love a person can have for his friends is to give his life for them.

A faithful friend is a sturdy shelter; he who finds one finds a treasure.

Cherish your friend, keep faith in him.
~ Sirach 27:17
