We just learned about the Eighth Commandment to not lie.
The ninth commandment that God gave to Moses is:
Thou shalt not covet thy neighbor’s house.
This means that if your friend or someone else has something that you would like to have,
don't sit and think about how much you want that thing, be happy with what you have.
(from: wikisource - Luther's Small Catechism)
(from: wikipedia - moses)
