Arcana Coelestia#4193
4193. 'And they ate there upon the heap' means making their; own that which came from Divine good. This is clear from the meaning of 'eating' as communication, a joining together, and a making one's own, dealt with in 2187, 2343, 3168, 3513 (end), 3596, 3832, and from the meaning of 'a heap' as good, dealt with immediately above in 4192, in this case Divine good.
Arcana Coelestia#3168
3168. 'And they ate and drank' means making one's own the good and truth introduced in this way. This is clear from the meaning of 'eating' as being communicated and joined together, thus being made one's own, dealt with in 2187, 2343, and more specifically (since 'eating' has reference to bread and 'bread' means good, 276, 680, 2165, 2177, 2187) making good one's own; and from the meaning of 'drinking' as being communicated and joined together, thus being made one's own, dealt with in 3089, and more specifically (since 'drinking' has reference to wine and 'wine' means truth, 1071, 1798) making truth one's own. The situation is as stated above in 3167, namely that when truth is introduced into good in the rational, more so when it is joined to it, the good and truth of the spiritual man, that is, spiritual things, become made over to the natural as its own.
