You shall not steal.So, again this one seems like a "no-brainer," but can it be that simple? Yes, it can. This doesn't only apply to physically taking something that isn't yours, though. It also extends to dealing treacherously, committing fraud, kidnapping, and swindling. The Israelites believed theft to be a step down the path of covetous desire that ultimately leads to murder.
Exodus 20:15 (ESV)
