Arcana Coelestia #3429
3429. 'And he called the name of it Sitnah' means their essential nature. This is clear from the meaning of 'calling the name' as the essential nature, dealt with in 144, 145, 1754, 1896, 2009, 2724, 3006, 3241, and from the meaning of 'Sitnah' in the original language as hostility, which is a further degree of denial.
Arcana Coelestia #1896
1896. 'Her name was Hagar' means the life of the exterior or natural man. This becomes clear from what has been stated already, and also from the meaning of Hagar' as a foreign woman or one living in foreign parts. 'Foreigners' represented people who were to receive instruction, and living in foreign parts represented instruction, and also rules of life, as shown already in 1463. When it is stated in the Word what a person's name is, as here, that 'her name was Hagar', it means that the name embodies something to which attention should be paid, for 'calling by name' is knowing a person's character, as shown already in 144, 145, 340. Not one particle exists in the Word without a reason and without meaning some real thing in the internal sense.
