The Didache, Didache 2
The second commandment of the teaching is this: Do not kill, do not commit adultery, do not corrupt children, do not fornicate, do not steal, do not practice magic, do not use potions, do not kill a child by abortion, and do not kill a newborn. Do not covet what belongs to your neighbor. Do not swear falsely, do not bear false witness, do not speak evil of anyone, and do not hold grudges. Do not be double‑minded or double‑tongued, because a double tongue is a snare of death. Let your word not be false or empty, but filled with action. Do not be greedy, a robber, a hypocrite, evil, or arrogant. Do not plot evil against your neighbor. Do not hate every person; instead, rebuke some, pray for others, and love some more than your own life.

Δευτέρα δὲ ἐντολὴ τῆς διδαχῆς: οὐ φονεύσεις, οὐ μοιχεύσεις, οὐ παιδοφθορήσεις, οὐ πορνεύσεις, οὐ κλέψεις, οὐ μαγεύσεις, οὐ φαρμακεύσεις, οὐ φονεύσεις τέκνον ἐν φθορᾷ, οὐδὲ γεννηθὲν ἀποκτενεῖς, οὐκ ἐπιθυμήσεις τὰ τοῦ πλησίον. οὐκ ἐπιορκήσεις, οὐ ψευδομαρτυρήσεις, οὐ κακολογήσεις, οὐ μνησικακήσεις. οὐκ ἔσῃ διγνώμων οὐδὲ δίγλωσσος: παγὶς γὰρ θανάτου ἡ διγλωσσία. οὐκ ἔσται ὁ λόγος σου ψευδής, οὐ κενός, ἀλλὰ μεμεστωμένος πράξει, οὐκ ἔσῃ πλεονέκτης οὐδὲ ἅρπαξ οὐδὲ ὑποκριτὴς οὐδὲ κακοήθης οὐδὲ ὑπερήφανος. οὐ λήψῃ βουλὴν πονηρὰν κατὰ τοῦ πλησίον σου. οὐ μισήσεις πάντα ἄνθρωπον, ἀλλὰ οὓς μὲν ἐλέγξεις, περὶ δὲ ὦν προσεύξῃ, οὓς δὲ ἀγαπήσεις ὑπὲρ τὴν ψυχήν σου.
