George Leo Haydock, on Exod 20:16

“Thou shalt not bear false witness against thy neighbour.”

“False. Calumniators were subjected to the law of retaliation, and were forced, by the Egyptians and others, to undergo the same punishment, which they would have inflicted upon others. This law is the guardian of good faith and honesty in all our dealings. It is explained more in detail [in] chap. xxiii. 1, and Leviticus xix. 11.”
