What does God forbid in the eighth commandment?

God forbids not only outright theft and robbery, punishable by law.¹ 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,² such as inaccurate measurements of weight, size, or volume; fraudulent merchandising; counterfeit money; excessive interest; or any other means forbidden by God.³ In addition God forbids all greed⁴ and pointless squandering of his gifts.⁵
