1. Does the eighth commandment concern our own and our neighbour's wealth and outward estate? Yes: for the earth God has given to the children of men, Ps. 115:16. Is it necessary there should be such a command? Yes: for every brother will utterly supplant, Jer. 9:4.
2. Is robbing God the worst theft? Yes: Will a man rob God? Yet ye have robbed me, Mal. 3:8, 9. And is justice to God the highest justice? Yes: Render to God the things that are God's, Matt. 22:21.
