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.

3018. Verse 2 And Abraham said to his servant, the oldest of his house, who administered all that he had, Put now your hand under my thigh.

'Abraham said to his servant, the oldest of his house' means the ordering and influx of the Lord into His Natural, meant by 'the servant, the oldest of the house'. 'Who administered all that he had' means the functions of the natural man. 'Put now your hand under my thigh' means being bound, as regards its power, to the good of conjugial love.
