Arcana Coelestia # 5408
5408. 'And [Joseph's ten brothers] went down' means an aim and endeavour - an aim and endeavour to acquire truths to itself, and to make these its own, through factual knowledge. This is evident from the meaning of 'going down' - going down to Egypt - as an aim and endeavour.
Exodus 2:23-25
23
It happened in the course of those many days, that the king of Egypt died, and the children of Israel sighed because of the bondage, and they cried, and their cry came up to God because of the bondage.
24
God heard their groaning, and God remembered his covenant with Abraham, with Isaac, and with Jacob.
25
God saw the children of Israel, and God was concerned about them.
