Matthew Poole and continuators on Esther 1:8

8 And the drinking was according to the law, none did compel : for so the king had appointed to all the officers of his house, that they should do according to every mans pleasure.

i. e. According to this Law which the King had now made▪ that none should compel another to drink more than he pleased▪ which the Persians, and other loose and heathenish Nations used to do; though that practice was connemned by the wise and sober Heathens, and among others by this great Prince. Or, no man did compel another to drink according to the Law, i. e. as by the Laws or Orders of the Persians prescribed and used in their Feasts they might have done, if not restrained by this Law.
