Arcana Coelestia # 3072
3072. 'Let her be the one whom You have appointed for Your servant Isaac' means the joining together of Divine truth and Divine Good in the Rational. This is clear from the meaning of 'appointing', that is to say, the woman, as joining together by means of a marriage covenant, and from the representation of 'Isaac' as the Divine good of the Rational, dealt with above in 3024. Rebekah - to whom 'her' refers here - represents Divine truth that was to be joined to the Divine Good of the Rational, as stated in various places above and as is evident from the details in the internal sense in this chapter.
Jehovah
The Lord, in the simplest terms, is love itself expressed as wisdom itself. In philosophic terms, love is the Lord's substance and wisdom is His form. Of course, we feel the Lord's love and hear His wisdom in many different ways, depending on our state in life and how receptive we are. That's why the Lord has so many different names in the Bible, and is referred to in so many different ways.
