What does God forbid in the eighth commandment?
God forbids not only outright theft and robbery, punishable by law.
But in God’s sight theft also includes all scheming and swindling in order to get our neighbor’s goods for ourselves, whether by force or means that appear legitimate, such as inaccurate measurements of weight, size, or volume; fraudulent merchandising; counterfeit money; excessive interest; or any other means forbidden by God.
In addition God forbids all greed and pointless squandering of His gifts.
What does God require of you in this commandment?
That I do whatever I can for my neighbor’s good, that I treat others as I would like them to treat me, and that I work faithfully so that I may share with those in need.
