In Genesis 12:9, 13:1, this symbolizes a state of clarity. (Arcana Coelestia 1458)

9658. 'Thus it shall be for them both; at the two corners they shall be' means a like joining together everywhere. This is clear from the meaning of 'both', or the two, as a joining together, dealt with above in 9655. Since things were to be the same at both corners, a like joining together everywhere is meant. For the paired boards at the two corners faced all four quarters - this was how the two legs at the corners were assembled - and to face all four quarters is to look everywhere. And since things were to be alike at both, a like joining together everywhere is meant.
