Flesh has several meanings just in its most obvious form. It can mean all living creatures as when the Lord talks about the flood "destroying all flesh"(Genesis 7:21), or it can mean all of mankind (Genesis 6:3), or it can mean something soft and yielding such as the heart of flesh to replace the stony heart (Ezekiel 11:19) But spiritually it means the loves that dwell in the will of a person, and seem to belong to that person, to be that person. This person may be one who has not started to regenerate (or never will), or one who is in the middle of the process, or one who is near the end. In the highest sense flesh means the loves that are in the Lord's will, which are divine. This meaning is clear in the Lord's words in the gospel of John (John 6:53-56).

3620. 'I loathe my life on account of the daughters of Heth' means a connection with natural truth from some other source. This is clear from the meaning of 'loathing one's life' as no connection, that is to say, of the truth of the natural with the truth of the rational - for when these two are not connected to each other it seems to the rational as though its own life were no life, as may be seen from what has been stated above in 3493; and from the meaning of 'the daughters of Heth' as affections for truth from a non-genuine source, in this case affections for natural truth, since Rebekah said this to Jacob who, as shown above, represents natural truth. For 'the daughters' means affections, see 2362, and 'Heth' or Hittite truth from a non-genuine source, 3470. From these meanings it is clear that 'I loathe my life on account of the daughters of Heth' means that there should not be any connection with the natural through truth which does not come from a genuine source, thus that no connection with natural truth from some other source should exist. The connection with natural truth is dealt with later on where Jacob's stay with Laban is the subject - that is to say, when truths from a common stem have been joined on to it. Since the truths which 'the daughters of Heth' represent did not come from that common stem no connection of them with natural truth was possible, because they were dissimilar and did not accord with it. Actually the spiritual Church among gentiles, 2913, 2956, is represented by 'the sons of Heth', but as the Word does not exist in that Church the Word is not the source of its truths.
