Arcana Coelestia # 6001
6001. 'And said, Jacob, Jacob' means made to natural truth. This is clear from the representation of 'Jacob' as natural truth, dealt with in 3305, 3509, 3525, 3546, 3599, 3775, 4009, 4234, 4520, 4578. The reason why the name 'Jacob' and not Israel is used is that natural truth and all that accompanies it must be introduced into the facts known to the Church, meant by Jacob's going down into Egypt together with his sons, see below in 6004.
Zechariah 14:7-9
7
It will be a unique day which is known to Yahweh; not day, and not night; but it will come to pass, that at evening time there will be light.
8
It will happen in that day, that living waters will go out from Jerusalem; half of them toward the eastern sea, and half of them toward the western sea; in summer and in winter will it be.
9
Yahweh will be King over all the earth. In that day Yahweh will be one, and his name one.
