Do not abandon an old friend, for a new one has not the same value. New wine, new friend; let them mature, then you will enjoy them with pleasure.
Do not envy the success of the sinner, you do not know what his end will be.
Do not take pleasure in what pleases the godless, remember that they will be punished before they die.
Keep well away from the man who has power to kill and you will not experience the fear of death. But if you go with him avoid all offense for fear that he will deprive you of life: realize that you are passing through deathtraps and that you are walking on top of the wall.
As far as you can, be sociable and take counsel with learned men.
Love to speak with intelligent men and let all your discourses be about the law of the Most High.
Let just men be your companions at table; take pride in your fear of the Lord.
An artisan is judged by his work and a leader of the community, by the wisdom of his words.
A talkative man is dreaded in his town and the gossip makes himself disliked.
Sirach 9:10-18
