Arcana Coelestia #3018
3018. Verse 2 And Abraham said to his servant, the oldest of his house, who administered all that he had, Put now your hand under my thigh.
'Abraham said to his servant, the oldest of his house' means the ordering and influx of the Lord into His Natural, meant by 'the servant, the oldest of the house'. 'Who administered all that he had' means the functions of the natural man. 'Put now your hand under my thigh' means being bound, as regards its power, to the good of conjugial love.
Ezekiel 1:13-15
13
As for the likeness of the living creatures, their appearance was like burning coals of fire, like the appearance of torches: [the fire] went up and down among the living creatures; and the fire was bright, and out of the fire went forth lightning.
14
The living creatures ran and returned as the appearance of a flash of lightning.
15
Now as I saw the living creatures, behold, one wheel on the earth beside the living creatures, for each of the four faces of it.
