So it is written:
Proverbs 11:The Lord detests dishonest scales, but accurate weights find favor with him.
Exodus 20: 15 Thou shalt not steal. 16 Thou shalt not bear false witness against thy neighbour.
17 Thou shalt not covet. . .
Levitcus 19:34The foreigner residing among you must be treated as your native-born. Love them as yourself, for you were foreigners in Egypt. I am the LORD your God.
But what people actually DO, is a different story.
