24. Verse 6 And God said, Let there be an expanse in the midst of the waters, and let there be a distinguishing of the waters from the waters.

After the Spirit of God, which is the Lord's mercy, has brought out into the daylight cognitions of truth and good, and has shed the light of dawn to reveal that the Lord does exist, and that He is good itself and truth itself, and that no good or truth exists except from the Lord, a distinction is at that point made between the internal man and the external man, and so between cognitions which reside with the internal man and the facts which belong to the external man. The internal man is called 'an expanse, and the cognitions residing with the internal man are called 'the waters above the expanse', while the facts belonging to the external man are called 'the waters below the expanse'.

[2] Until his regeneration starts a person is not aware of even the existence of the internal man, let alone the identity of the internal man. Submerged in bodily and worldly concerns he imagines there is no difference between the two. Furthermore he has submerged in those same concerns the things that belong to the internal man and has made one thorough obscurity out of things that are distinct and separate. For this reason it is first said, 'Let there be an expanse in the midst of the waters', and then, 'Let there be a distinguishing of the waters from the waters', and not a distinguishing of the waters. But this is followed immediately by the statement, Verses 7-8, And God made the expanse and He made a distinction between the waters that were under the expanse and the waters that were above the expanse; and it was so. And God called the expanse Heaven.

[3] The second thing therefore that a person notices when being regenerated is that he is starting to become aware of the existence of the internal man, or that what reside in the internal man are goods and truths which are the Lord's alone. And since the external man during regeneration is such as still imagines that he is the source of the good deeds he performs, or of the truth he utters, and since such a person, by means of them, is led by the Lord to do good and to speak truth as if they were his own, therefore the identification of those under the expanse comes first, and the identification of those above the expanse follows. It is also a heavenly arcanum that the Lord uses those things that are man's own - both his illusions of the senses and his desires - to lead and direct him towards the things that are goods and truths. Every single movement of regeneration is accordingly a progression from evening to morning - from external man to internal, that is, from earth to heaven. This is why the expanse, or internal man, is now called 'heaven'.

8267. 'And song is Jah' means that the source of the whole of faith and of the glory resulting from it is Divine Truth which originates in Him. This is clear from the meaning of 'song', in reference to Jehovah, as an ascription of glory to the Lord, dealt with above in 8261. But when used in reference to man, as it is here, it means glory existing as a result of faith, and so faith from which glory results; for the whole of the glory which man has exists as a result of faith in the Lord, since faith which really is faith has its origin in the Lord, so that the Lord is within faith and consequently glory itself is also present. A further reason why man's glory is a result of faith is that Divine Truth, the source and conveyor of faith, appears before angels' eyes as light, and also as the brightness and radiance of light. This radiance, along with the magnificent scenes in heaven that are products of the light, is called the glory, which is accordingly nothing other than Divine Truth, and so nothing other than faith. This then explains why 'song', in reference to man, means glory resulting from faith.

[2] 'Jah' means Divine Truth that emanates from the Lord's Divine Human. This is because Jah is derived from Jehovah, and the name Jah is used because it does not mean Being (Esse) but the Coming-into-Being arising from Being (Existere ex Esse); for Divine Truth is the Coming-into-Being (Existere), whereas Divine Good is Being (Esse), see 6880. This also is why the expression 'song is Jah' is used, for 'song' means faith that is a product of Divine Truth. 'Jah' again means Divine Truth in David,

Sing to God, praise His name; extol Him who rides on the clouds by His name Jah, and exult before Him. Psalms 68:4.

Praising and extolling God 'by His name Jah' is doing so through Divine Truth. Again in the same author,

In distress I called on Jah; Jah answered me in a broad place. Jehovah helped me. My strength and song is lain. I shall not die, but live, and declare the works of Jah. I will enter through the gates of righteousness, and confess Jah. Psalms 118:5, 13-14, 17, 19.

Here 'Jah' is the Lord in respect of Divine Truth. Jah has the same meaning in the exclamation Hallelujah, at Psalms 105:45; 106:1, 48; 111:1; 112:1; 113:1, 9; 115:17-18; 116:19.
