Jamieson-Fausset-Brown Bible Commentary

5. Now in Shushan the palace there was a certain Jew-Mordecai held some office about the court. But his "sitting at the king's gate" (Es 2:21) does not necessarily imply that he was in the humble condition of a porter; for, according to an institute of Cyrus, all state officers were required to wait in the outer courts till they were summoned into the presence chamber. He might, therefore, have been a person of some official dignity. This man had an orphan cousin, born during the exile, under his care, who being distinguished by great personal beauty, was one of the young damsels taken into the royal harem on this occasion. She had the good fortune at once to gain the good will of the chief eunuch [Es 2:9]. Her sweet and amiable appearance made her a favorite with all who looked upon her (Es 2:15, last clause). Her Hebrew name (Es 2:7) was Hadassah, that is, "myrtle," which, on her introduction into the royal harem, was changed to Esther, that is, the star Venus, indicating beauty and good fortune [Gesenius].

Matthew Henry's Concise Commentary

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.
