In Genesis 21:7, this signifies to implant truth from good, or something spiritual from a celestial origin. (Arcana Coelestia 2643)

In Psalm 8:2, this signifies that praise can come to the Lord only through innocence, for this alone effects all communication and all influx. (Arcana Coelestia 5236[4]) 'The nurse,' in Genesis 24:59, signifies a state of innocence. 'The nurse,' in Genesis 35, signifies hereditary evil. 'A nurse,' as she feeds and nurses an infant, properly signifies the introduction of innocence by the celestial spiritual. But when 'Deborah, the nurse of Rebecca died and was buried,' it signifies that hereditary evil which the Lord received from His mother, which was nourished from infancy just like with other people, was later totally expelled forever.

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.
