Arcana Coelestia # 2841
2841. 'The angel of Jehovah called to Abraham a second time out of heaven' means a still greater comfort received by the Lord [from the Divine]. This is clear from the meaning of 'calling out of heaven' as giving comfort to, and from the meaning of 'the angel of Jehovah' as the Lord's Divine itself, dealt with above in 2821, where the same words occur. The expression a second time is used here because a greater comfort is received. The comfort received first is contained in verses 12-14, where Divine providence is the subject, that comfort being that those members of the human race who are called spiritual would be adopted. The second comfort, which is greater, is contained in the verses which follow below - in verses 17-18, and those that follow to the end of the chapter - the comfort in this case being that those spiritual ones would be multiplied as the stars of the heavens and as the sand on the seashore, and that not only those people would be saved but also all in whom goodness may be found. These things were the objects of the Lord's love, and therefore such things brought Him comfort. No one finds any comfort except in the things which are the objects of his love.
Deuteronomy 5:22-24
22
These words Yahweh spoke to all your assembly on the mountain out of the midst of the fire, of the cloud, and of the thick darkness, with a great voice: and he added no more. He wrote them on two tables of stone, and gave them to me.
23
It happened, when you heard the voice out of the midst of the darkness, while the mountain was burning with fire, that you came near to me, even all the heads of your tribes, and your elders;
24
and you said, "Behold, Yahweh our God has shown us his glory and his greatness, and we have heard his voice out of the midst of the fire: we have seen this day that God does speak with man, and he lives.
