'Compulsion' in the Bible

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

Then the Lord said to Moses, “Now you shall see what I will do to Pharaoh; for under compulsion he will let them go, and under compulsion he will drive them out of his land.”

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.
