3377. Verses 4-5 And I will cause your seed to multiply as the stars of heaven, and I will give to your seed all these lands; and in your seed all the nations of the earth will be blessed, because Abraham hearkened to My voice and practiced My observances, My commandments, My statutes, and My laws.

'I will cause your seed to multiply as the stars of heaven' means truths and cognitions of faith 'And I will give to your seed all these lands' means derivative Churches. 'And in your seed all the nations of the earth will be blessed' means all with whom good is present, both inside and outside the Church. 'Because Abraham hearkened to My voice' means the union of the Lord's Divine Essence with the Human Essence by means of temptations. 'And practiced My observances, My commandments, My statutes, and My laws' means through revelations constantly coming from Himself.

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.
