'Compulsion' in the Bible

But I know that the king of Egypt will not permit you to go, except under compulsion.

The LORD told Moses, "Now you're about to see what I'll do to Pharaoh. Indeed, he'll send them out under compulsion and he'll drive them out of his land violently."

The drinking was done according to the law, there was no compulsion, for so the king had given orders to each official of his household that he should do according to the desires of each person.
