Arcana Coelestia # 3765
3765. And behold a well. That this signifies the Word, is evident from the signification of a “well,” as being the Word, and also doctrine from the Word (n. 2702, 3096, 3424). The Word is here called a well,” because the natural is treated of, which regarded in itself apprehends the Word solely as to the literal sense; whereas the Word is called a “fountain” when the rational is treated of, by which the Word can be perceived according to the internal sense.
Genesis 26:18-22
18
Isaac dug again the wells of water, which they had dug in the days of Abraham his father. For the Philistines had stopped them after the death of Abraham. He called their names after the names by which his father had called them.
19
Isaac's servants dug in the valley, and found there a well of springing water.
20
The herdsmen of Gerar argued with Isaac's herdsmen, saying, "The water is ours." He called the name of the well Esek, because they contended with him.
21
They dug another well, and they argued over that, also. He called its name Sitnah.
22
He left that place, and dug another well. They didn't argue over that one. He called it Rehoboth. He said, "For now Yahweh has made room for us, and we will be fruitful in the land."
