H. The Eighth Commandment

You must not tell lies about your neighbor.((Exodus 20:16))

Q. What does this mean?

A. We must fear and love God, so that we will not deceive by lying, betraying, slandering or ruining our neighbor’s reputation, but will defend him, say good things about him, and see the best side of everything he does.
