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.

2305. There are certain people who identify innocence with early childhood, for the reason that the Lord, when speaking about young children, said that heaven consisted of such, and that those who do not become as young children cannot enter the kingdom of heaven. But those who think in this fashion do not know the internal sense of the Word, nor thus what is meant by early childhood. 'Early childhood' is used to mean the innocence that belongs to intelligence and wisdom, the nature of which is such that they acknowledge that they possess life solely from the Lord and that the Lord is their one and only Father; for a person is human because of intelligence and wisdom - essentially truth and good respectively - which people have solely from the Lord. Innocence itself, which in the Word is called early childhood, exists and resides nowhere else than within wisdom, so much so that the wiser anyone is the more innocent he is. Consequently the Lord is Innocence itself, because He is Wisdom itself.
