Esther 1:19 - Clarke's commentary and critical notes on the Bible

If it please the king, let there go a royal commandment from him, and let it be written among the laws of the Persians and the Medes, that it be not altered, That Vashti come no more before king Ahasuerus; and let the king give her royal estate unto another that is better than she. That it be not altered - Let it be inserted among the permanent laws, and made a part of the constitution of the empire. Perhaps the Persians affected such a degree of wisdom in the construction of their laws, that they never could be amended, and should never be repeated. And this we may understand to be the ground of the saying, The laws of the Medes and Persians, that change not.
