'Demands' in the Bible

“When men get in a fight and hit a pregnant woman so that her children are born prematurely but there is no injury, the one who hit her must be fined as the woman’s husband demands from him, and he must pay according to judicial assessment.

By justice a king brings stability to a land,but a man who demands “contributions”demolishes it.

But He answered them, “An evil and adulterous generation demands a sign, but no sign will be given to it except the sign of the prophet Jonah.

As the crowds were increasing, He began saying: “This generation is an evil generation. It demands a sign, but no sign will be given to it except the sign of Jonah.

So, when Gentiles, who do not have the law, instinctively do what the law demands, they are a law to themselves even though they do not have the law.
