Matthew Henry's Concise Commentary

8:15-17 Mordecai's robes now were rich. These things are not worth notice, but as marks of the king's favour, and the fruit of God's favour to his church. It is well with a land, when ensigns of dignity are made the ornaments of serious piety. When the church prospers, many will join it, who will be shy of it when in trouble. When believers have rest, and walk in the fear of the Lord, and the comfort of the Holy Ghost, they will be multiplied. And the attempts of Satan to destroy the church, always tend to increase the number of true Christians.
