And in every province, and in every city, whithersoever the king's commandment and his decree came, the Jews had joy and gladness, a feast and a good day. And many of the people of the land became Jews; for the fear of the Jews fell upon them. (Esther 8:17 KJV)​
As it proclaims holiness of heart and life, which nothing but the Spirit of God can produce, so it is the Spirit of God alone that can persuade the understanding and change the heart. If the kingdom of Christ were of this world, then would his servants fight. (Adam Clarke)​
