1 Clement 30:1-10
1Seeing, therefore, that we are the portion of the Holy One, let us do all those things which pertain to holiness, avoiding all evil-speaking, all abominable and impure embraces, together with all drunkenness, seeking after change, all abominable lusts, detestable adultery, and execrable pride.
2"For God," saith [the Scripture], "resisteth the proud, but giveth grace to the humble."
3Let us cleave, then, to those to whom grace has been given by God.
4Let us clothe ourselves with concord and humility, ever exercising self-control, standing far off from all whispering and evil-speaking, being justified by our works, and not our words.
5For [the Scripture] saith, "He that speaketh much, shall also hear much in answer.
6And does he that is ready in speech deem himself righteous?
7Blessed is he that is born of woman, who liveth but a short time: be not given to much speaking."
8Let our praise be in God, and not of ourselves; for God hateth those that commend themselves.
9Let testimony to our good deeds be borne by others, as it was in the case of our righteous forefathers.
10Boldness, and arrogance, and audacity belong to those that are accursed of God; but moderation, humility, and meekness to such as are blessed by Him.
