Romans 13:8-9

8Owe nothing to anyone except to love and seek the best for one another; for he who [unselfishly] loves his neighbor has fulfilled the [essence of the] law [relating to one’s fellowman].

9The commandments, “You shall not commit adultery, you shall not murder, you shall not steal, you shall not covet,” and any other commandment are summed up in this statement: “You shall love your neighbor as yourself.”
