6993. And I will be with thy mouth, and will teach thee what thou shalt speak. That this signifies the Divine in each and all things which proceed from the Divine Human is evident from the signification of "being with the mouth," when said by Jehovah, as being to be with what he utters (that by the "mouth" is signified utterance, see n. 6987, 6988), and as these things are said to Moses, by whom is represented the Lord as to the law Divine in the Divine Human, therefore by "I will be with thy mouth" is signified the Divine in the things which proceed from the Divine Human; and from the signification of "teaching thee what thou shalt say" as being to proceed; for by "teaching" and by "speaking" is signified to flow in, and when said of the Divine of the Lord, it signifies to proceed. For from the Lord's Divine Human itself proceeds Divine truth, which is called the "Holy Spirit"; and because when the Lord was in the world He was Himself the Divine truth, He Himself taught the things that were of love and faith, and at that time not by the Holy Spirit, as He Himself teaches in John:
The Holy Spirit was not yet, because Jesus was not yet glorified (John 7:39).
But after the Lord even as to the Human was made Jehovah, that is, Divine good, which was after the resurrection, then He was no longer Divine truth, but this proceeded from His Divine good. That the "Holy Spirit" is the Divine truth which proceeds from the Lord's Divine Human, and not any spirit or spirits from eternity, is very evident from the Lord's words in the passage above cited, namely, that "the Holy Spirit was not yet"; also that a spirit cannot himself proceed, but the holy of the spirit, that is, the holy which proceeds from the Lord, and which a spirit utters (see also n. 6788).
 From all this then it follows that the whole trinity, namely, Father, Son, and Holy Spirit, is perfect in the Lord, and thus that there is one God, and not three, who being distinct as to persons are said to constitute one Divine. That in the Word mention has been made of "Father, Son, and Holy Spirit" was that men might acknowledge the Lord and also the Divine in Him. For man was in such thick darkness, as he also is at this day, that otherwise he would not have acknowledged any Divine in the Lord's Human; for this, being wholly incomprehensible, would have been to him above all belief. And moreover it is a truth that there is a Trine, but in one, namely, in the Lord; and it is also acknowledged in Christian churches that the Trine dwells perfectly in Him. Moreover, the Lord openly taught that He was one with the Father (John 14:9-12); and that the holy, which the Holy Spirit speaks, is not of the Spirit but of the Lord; in John:
The Paraclete, the Spirit of truth, will not speak from Himself, but whatever He hears, He will speak. He will glorify Me, for He will take of what is Mine, and announce it to you (John 16:13-14).
That the "Paraclete" is the Holy Spirit is said in John 14:26.
