21 After these things, when the king's feelings were calmer, the thought of Vashti and what she had done and the order he had made against her, came back to his mind. 2 Then the servants who were waiting on the king said to him, Let search be made for some fair young virgins for the king: 3 Let the king give authority to certain men in all the divisions of his kingdom, to get together all the fair young virgins and send them to Shushan, the king's town, to the women's house, under the care of Hegai, the king's servant, the keeper of the women: and let the things needed for making them clean be given to them; 4 And let the girl who is pleasing to the king be queen in place of Vashti. And the king was pleased with this suggestion; and he did so.

Commentary on Esther 2:1-20
(Read Esther 2:1-20)
We see to what absurd practices those came, who were destitute of Divine revelation, and what need there was of the gospel of Christ, to purify men from the lusts of the flesh, and to bring them back to the original institution of marriage. Esther was preferred as queen. Those who suggest that Esther committed sin to come at this dignity, do not consider the custom of those times and countries. Every one that the king took was married to him, and was his wife, though of a lower rank. But how low is human nature sunk, when such as these are the leading pursuits and highest worldly happiness of men! Disappointment and vexation must follow; and he most wisely consults his enjoyment, even in this present life, who most exactly obeys the precepts of the Divine law. But let us turn to consider the wise and merciful providence of God, carrying on his deep but holy designs in the midst of all this. And let no change in our condition be a pretext for forgetting our duties to parents, or the friends who have stood in their place.
