Arcana Coelestia #6552
6552. Verse 14 And Joseph returned to Egypt, he and his brothers, and all who went up with him to bury his father, after he had buried his father.
'And Joseph returned to Egypt, he and his brothers' means the life of the internal celestial, and of the truths of faith present within factual knowledge. 'And all who went up with him to bury his father' means all that contributes to regeneration. 'After he had buried his father' means to restore the Church to life.
Swear
In Genesis 21:23, this signifies affirmation.
The Lord swearing by himself signifies that divine truth testifies, for He is divine truth itself, and this testifies from itself and means itself. It says 'Jehovah swears' because the children of Israel had a representative church, and so the Lord's conjunction with the church was represented in a covenant similar to two people swearing their trust. This is why swearing was used to seal a covenant or deal. When 'Jehovah swears' it does not mean that He really did swear, but that divine truth testifies or bears testimony to the things asserted.
