29 And if further a man peruse all the books of the Prophets, both of the Twelve, and of the others, he will find many testimonies concerning. the Holy Ghost; as when Micah says in the person of God, surely I will perfect power by the Spirit the Lord; and Joel cries, And it shall come to pass afterwards, says God, that I will pour out My Spirit upon all flesh, and the rest; and Haggai, Because I am with you, says the Lord of Hosts; and My Spirit remains in the midst of you; and in like manner Zechariah, But receive My words and My statutes which I command by My Spirit, to My servants the Prophets; and other passages.
