[827] **One should depart from false speech (mosavajja):** false speech (musāvāda) is what is called deceitful speech (mosavajja). Here someone, gone to a council, or gone to an assembly, or gone to the midst of relatives, or gone to the midst of a guild, or gone to the midst of the royal court, being brought forward and questioned as a witness: "Come, good man, tell what you know" — he, not knowing, says "I know"; or knowing, says "I do not know"; or not seeing, says "I see"; or seeing, says "I do not see." Thus for his own sake, or for the sake of another, or for the sake of some trifling material gain, he knowingly speaks deliberate falsehood. This is called false speech. Moreover, false speech comes about in three ways, in four, five, six, seven, or eight ways … in these eight ways false speech comes about. **One should depart from false speech** means: one should not be led along by false speech, should not be carried away, should not be swept away; one should abandon false speech, dispel it, make an end of it, bring it to non-existence; one should be one who is far from false speech, abstaining, refraining, gone out from it, released from it, freed from it, detached from it; one should dwell with a mind made free of boundaries. Hence, "one should depart from false speech."
