3023. 'I will make you swear by Jehovah, the God of heaven and the God of the earth' means an utterly sacred binding to the Divine which existed in highest things and in the things derived from these. This is clear from the meaning of 'making someone swear by' as binding by means of an oath, for to swear by is nothing else than to be bound to; and this bond is utterly sacred when one swears 'by Jehovah, the God of heaven and the God of the earth', that is, when one is bound to the Divine above and beneath, or what amounts to the same, to the Divine which exists in highest things and in the things derived from these. Since 'Jehovah the God of heaven' is used in reference to the Lord, it means Jehovah Himself, who is called 'the Father', from whom the Lord was conceived and so who was the Lord's Divine Essence; for His very conception transmitted that very Essence from which He had His being. 'Jehovah the God of the earth' means in this case Jehovah who is called 'the Son', and so means His Human Essence. The Human Essence came into being from the Divine Essence when the Lord made that Human Essence Divine also. Thus 'Jehovah the God of heaven' means the Divine as it exists in highest things, while 'Jehovah the God of the earth' means the Divine as it exists in the things derived from these. The Lord however is called 'Jehovah, the God of heaven' by virtue of His Divine in the heavens, and 'the God of the earth' by virtue of His Divine on earth. The Divine in the heavens is also that which resides with man in his internals, whereas the Divine on earth is that which does so in his externals. For man's internals constitute his 'heaven' because through them he is linked to angels, whereas his externals constitute his 'earth' because through them he is linked to men, 82, 913, 1411, 1733. When a person has been regenerated his internals flow into his externals, and externals exist from internals. From this one may also know what the internals of the Church are and what its externals.

2083. 'And you will call his name Isaac' means the Divine Rational. This is clear from Isaac's representation and also from the meaning of his name in the internal sense.

From Isaac's representation: As stated frequently already, 'Abraham' represents the Lord's Internal Man, 'Isaac' His Rational Man, and 'Jacob' His Natural Man. The Lord's Internal Man was Jehovah Himself. Because the Rational Man was conceived from the influx of the Internal Man into the External Man's affection for knowledge, 1896, 1902, 1910, it originated in the Divine thus joined to the Human. Consequently the first rational represented by 'Ishmael' was human, but it was made Divine by the Lord, and is then represented by 'Isaac'.

From the meaning of his name: He was given the name Isaac from the word for 'laughter', and because laughter in the internal sense means the affection for truth, which belongs to the rational, as shown above in 2072, Isaac accordingly here means the Divine Rational.

[2] From His own power the Lord made Divine everything that was human with Him. Thus He made not only the rational Divine but also the sensory part, interior and exterior, and so the body itself. In this way He united the Human to the Divine. It has been shown already that not only the rational, but also the sensory part, and so the whole body also was made Divine and Jehovah. This may also become clear to anyone from the fact that He alone has risen as to the body from the dead, and sits at the right hand of the Divine Power both with His entire Divine and with His entire Human. 'Sitting at the right hand of Divine power' means having all power in heaven and on earth.
