Arcana Coelestia # 10091
10091. And thou shalt sanctify the breast of the waving. That this signifies the Divine spiritual acknowledged in heaven and in the church, is evident from the signification of “sanctifying,” as being to represent the Lord and the holy things which are from Him (see n. 9956, 9988); from the signification of “the breast,” as being the Divine spiritual in heaven (n. 10087); and from the signification of “the waving,” as being vivification through acknowledgment (see n. 10083, 10089). The Divine spiritual is Divine truth in the middle or second heaven, which heaven is also called the spiritual kingdom.
Joshua 3:11-13
11
Behold, the ark of the covenant of the Lord of all the earth passes over before you into the Jordan.
12
Now therefore take twelve men out of the tribes of Israel, for every tribe a man.
13
It shall come to pass, when the soles of the feet of the priests who bear the ark of Yahweh, the Lord of all the earth, rest in the waters of the Jordan, that the waters of the Jordan will be cut off, even the waters that come down from above; and they shall stand in one heap."
