Thou and thy father’s house shall be destroyed - i. e. “a divine vengeance will overtake thee and thine, if thou neglectest thy plain duty.” Though the name of God is not contained in the Book of Esther, there is in this verse a distinct, tacit allusion to God’s promises, and to the direction of human events by Divine Providence.
