You shall not steal, neither deal falsely, neither lie one to another.
All Commentaries on Leviticus 19:11 Go To Leviticus 19
George Leo Haydock
Lie. "When no injury is done to another, it is a great question whether a lie can ever be justified. The case would perhaps be easily decided, if we considered the commandments alone, and not the examples "of those holy men who seem to have sometimes thought it lawful. (St. Augustine, q. 68) But is it not better to allow that these were under an in culpable mistake, than to defend one fault, because it is not attended with the guilt of another, by hurting others? Even lies of jest and of excuse, are contrary to the gravity and open-dealing of a Christian; and God never speaks of lying without marks of disapprobation. (Haydock)
Hebrew, "you shall not deny, or extenuate yourselves "pretending that you cannot give alms. (Oleaster)
