Arcana Coelestia # 6171
6171. 'And they had a possession in it' means given and set in order thus by the internal. This is clear from the meaning of 'a possession' as the position spiritual life occupies, dealt with in 6103; and since Joseph was the one who gave them that possession, verse 11, the giving and setting in order of that position by the internal is meant. It follows from the whole train of thought that this is what is meant.
Jacob's ladder
The truths of a person's early and later childhood serve the angels of God 'to go up on a ladder' from earth to heaven. But later, the truths of his adult life serve the angels of God 'to come down on the ladder' from heaven to earth.
