21 These memorials that I have written unto you, my beloved, concerning Jesus Who was persecuted, and the righteous who were persecuted, are in order that those who today are persecuted for the sake of the persecuted Jesus, may be comforted, for He wrote for us and comforted us Himself; for He said:— If they have persecuted Me, they will also persecute you. And because of this they will persecute you, that you are not of the world, even as I was not of it. For He wrote before for us:— Your fathers and your brothers and your family will deliver you up, and all men shall hate you for My name's sake. And again He taught us:— When they shall bring you before rulers and before magistrates, and before kings that hold the world, meditate not before the time what you shall say, and how you shall make defence; and I will give you a mouth and wisdom, that your enemies may not be able to overcome you, because it is not you that speak, but the Holy Spirit of your Father; He shall speak in you. This is the spirit which spoke by the mouth of Jacob to Esau, his persecutor; and the spirit of wisdom which spoke before Pharaoh by the mouth of the persecuted Joseph; and the spirit which spoke by the mouth of Moses in all the prodigies which he did in the land of Egypt, and the spirit of knowledge which was given to Joshua, the son of Nun, when Moses laid his hand upon him, so that the nations which persecuted him came to a complete end before him; and the spirit that uttered psalms by the mouth of the persecuted David, by which he used to sing psalms and soothe Saul his persecutor from the evil spirit; and the spirit which clothed Elijah, and through him reproved Jezebel and Ahab his persecutor; and the spirit which spoke in Elisha, and prophesied and made known to the king his persecutor about all that was to happen thereafter; and the spirit which was fervent in the mouth of Micaiah when he reproved Ahab his persecutor saying:— If you shall at all return back, the Lord has not spoken by me; and the spirit which strengthened Jeremiah, so that he stood boldly, and by it reproved Zedekiah; and the spirit that preserved Daniel and his brethren in the land of Babylon; and the spirit that delivered Mordecai and Esther in the place of their captivity.
