6993. 'And I will be with your mouth, and teach you the things you will speak' means the Divine in every single thing that emanates from the Divine Human. This is clear from the meaning of 'being with the mouth', when said by Jehovah, as being with the things it utters ('mouth' meaning utterance, see above in 6987, 6988), and since these words are addressed to Moses, who represents the Lord in respect of the law of God in the Divine Human, 'I will be with your mouth' means the Divine in the things that emanate from the Divine Human; and from the meaning of 'teaching you the things you will speak' as emanating. For 'teaching and 'speaking' mean flowing in; but when they are used in reference to the Lord's Divine, emanating is meant. For from the Lord's Divine Human emanates Divine Truth, which is called the Holy Spirit. And since the Lord when He was in the world was Himself Divine Truth, He taught matters of love and faith. He did not do so at that time through the Holy Spirit, as He teaches in John,
The Holy Spirit was not yet because Jesus was not yet glorified. John 7:39.
But after the Lord had become Jehovah, that is, Divine Good, in respect of the Human also, which was after the Resurrection, He was no longer Divine Truth. This now emanated instead from His Divine Good. The fact that the Holy Spirit is Divine Truth which emanates from the Lord's Divine Human, and not any spirit or spirits existing from eternity, is plainly evident from the Lord's words in the text quoted above - 'the Holy Spirit was not yet' - as well as from the consideration that a spirit himself cannot emanate from Him, only that which is holy with a spirit, that is, something holy which emanates from the Lord and is uttered by the spirit. See also 6788.
[2] From all this it now follows that within the Lord the entire Trinity is complete; that is to say, within Him are Father, Son, and Holy Spirit, and thus that there is one God, not three who, though persons distinct from one another, are said to constitute one Deity. In the Word the names Father, Son, and Holy Spirit were used in order that people might acknowledge the Lord and also the Divine within Him. For mankind was in such thick darkness, as it also is at the present day, that it could not in any other way have acknowledged anything Divine in the Lord's Human; being wholly incomprehensible to them it would have been entirely beyond belief. Furthermore the truth is that there is a Trinity, but within one, who is the Lord; and Christian Churches also acknowledge that the Trinity resides within Him in completeness. In addition the Lord explicitly taught that He was one with the Father, John 14:9-12, and that what is holy, which is spoken by the Holy Spirit, is not the Spirit's but the Lord's, in John,
The Paraclete, the Spirit of Truth, will not speak from Himself, but whatever He hears He will speak. He will glorify Me, because He will take of what is Mine and declare it to you. John 16:13, 14.
The fact that 'the Paraclete' is the Holy Spirit is stated in John 14:26.
