3621. 'If Jacob takes a wife from the daughters of Heth' means that natural truth ought not to be associated with them. This is clear from the meaning of 'taking a wife' as being associated, and from the meaning of 'the daughters of Heth' as affections for truth from a non-genuine source, dealt with just above in 3620, or what amounts to the same, as [mere] truth, for truth devoid of affection is not joined, 3066, 3336. What is implied in all this is clear from what has been stated just above about the daughters of Heth.

In Zechariah 8:12, 'the vine shall give her fruit, and the ground her increase,' signifies that the spiritual affection of truth produces the good of charity, and the natural affection of good and truth produces the works of charity.
