Deuterocanon

Sirach 4:20-31

20 Watch for the opportune time, and beware of evil,
and do not be ashamed to be yourself.
21 For there is a shame that leads to sin,
and there is a shame that is glory and favor.
22 Do not show partiality, to your own harm,
or deference, to your downfall.
23 Do not refrain from speaking at the proper moment,
and do not hide your wisdom.
24 For wisdom becomes known through speech,
and education through the words of the tongue.
25 Never speak against the truth,
but be ashamed of your ignorance.
26 Do not be ashamed to confess your sins,
and do not try to stop the current of a river.
27 Do not subject yourself to a fool,
or show partiality to a ruler.
28 Fight to the death for truth,
and the Lord God will fight for you.
29 Do not be reckless in your speech,
or sluggish and remiss in your deeds.
30 Do not be like a lion in your home,
or suspicious of your servants.
31 Do not let your hand be stretched out to receive
and closed when it is time to give.

Didache 4:1-14

1. My child, thou shalt remember, day and night, him who speaks the word of God to thee, and thou shalt honor him as the Lord, for where the Lord's nature is spoken of, there is he present.
2. And thou shalt seek daily the presence of the saints, that thou mayest find rest in their words.
3. Thou shalt not desire a schism, but shalt reconcile those that strive. Thou shalt give righteous judgement; thou shalt favor no mans person in reproving transgression.
4. Thou shalt not be of two minds whether it shall be or not.
5. Be not one who stretches out his hands to receive, but shuts them when it comes to giving.
6. Of whatsoever thou hast gained by thy hands thou shalt give a ransom for thy sins.
7. Thou shalt not hesitate to give, nor shalt thou grumble when thou givest, for thou shalt know who is the good Paymaster of the reward.
8. Thou shalt not turn away the needy, but shalt share everything with thy brother, and shalt not say it is thine own, for if you are sharers in the imperishable, how much more in the things which perish?
9. Thou shalt not withhold thine hand from thy son or from thy daughter, but thou shalt teach them the fear of God from their youth up.
10. Thou shalt not command in thy bitterness thy slave or thine handmaid, who hope in the same God, lest they cease to fear the God who is over you both; for he comes not to call men with respect of persons, but those whom the Spirit has prepared.
11. But do you who are slaves be subject to your master, as to God's representative, in reverence and fear.
12. Thou shalt hate all hypocrisy, and everything that is not pleasing to the Lord.
13. Thou shalt not forsake the commandments of the Lord, but thou shalt keep what thou didst receive, "Adding nothing to it and taking nothing away."
14. In the congregation thou shalt confess thy transgressions, and thou shalt not betake thyself to prayer with an evil conscience. This is the way of life.
