Apostolic Constitutions, Book VII 5
1You shall not be an hypocrite, lest your portion be with them. You shall not be ill-natured nor proud: for God resists the proud. You shall not accept persons in judgment; for the judgment is the Lord's. You shall not hate any man; you shall surely reprove your brother, and not become guilty on his account; and, Reprove a wise man, and he will love you. Eschew all evil, and all that is like it: for says He, Abstain from injustice, and trembling shall not come near you. Be not soon angry, nor spiteful, nor passionate, nor furious, nor daring, lest you undergo the fate of Cain, and of Saul, and of Joab: for the first of these slew his brother Abel, because Abel was found to be preferred before him with God, and because Abel's sacrifice was preferred; the second persecuted holy David, who had slain Goliah the Philistine, being envious of the praises of the women who danced; the third slew two generals of armies — Abner of Israel, and Amasa of Judah.
