The Hebrew of the Old Testament has six different common words which are generally translated as "wife," which largely overlap but have different nuances. Swedenborg uses two different Latin words, which largely overlap but have different nuances. Meanwhile, "wife" is often paired with "man" or "husband," which are also catch-all translations for a basket of Hebrew and Latin terms. So it's hard to pin down one universal meaning for "wife"; context and subject matter have a large effect.

In general, though, marriage in the Bible represents the union we all seek between our hearts and our minds. If we know what is right and pursue it faithfully, the Lord will ultimately help us love doing what is good, and the two aspects of ourselves will be unified. On a higher level, marriage represents the union we can have with the Lord, both individually and collectively as a church. As an intrinsic part of the marriage, the wife plays a key role in that meaning. But that meaning is different depending on what is being described.

If the marriage is describing a person who is spiritual in nature – "spiritual" being the second degree of heavenly life, in which people are led by intellect and knowledge with the desire for good following – the wife represents the desire for good, the affections that drive the person. If the marriage is describing someone who is celestial in nature – "celestial" being the highest degree of heavenly life, in which people are led from love, with the intellect and ideas following – the wife represents the true ideas held by the person or church. If the marriage is describing the union between the Lord and the church, the wife represents the church.

In a way, these are symbolic meanings that actually have little to do with gender. When "wife" describes a church, obviously that church can include both male and female people. When "wife" describes an aspect of a person, that person can obviously be either male or female.

3399. The expression 'lying with a wife' means in the internal sense perverting and adulterating truth, here truth that is Divine, because 'a wife' - Rebekah - represents Divine Truth, as shown above. This may be seen from the consideration that instances of lying together, adultery, and prostitution in the Word do not mean anything other than perversions of good and falsifications of truth, as shown in 2466, 2729. The reason why they do so is that all adultery is absolutely contrary to conjugial love, so much so that it is destructive of it; and conjugial love originates in the marriage of good and truth, 2508, 2618, 2727-2759, 3132. Consequently things that are contrary to good and truth, or that destroy them, are in the Word called forms of adultery.

[2] But it should be realized that those who belong to the spiritual Church are not able to adulterate good to such an extent that they profane it, for the reason that they are not able to receive good so far as to perceive it, as those who are celestial do. They are able however to profane truth because they are able to acknowledge it. Yet in the final period of the Church they are not able even to acknowledge truth, because at that time universal disbelief prevails concerning the Lord, concerning life after death, and concerning the internal man. And the disbelief which reigns universally makes it impossible for them to penetrate into the interior truths of faith. That which prevails with everyone universally limits them and keeps them back from entering more deeply into such things, even when the person is unaware of that universal disbelief and also when he supposes that he does believe.

[3] But those who are able to profane good are such as belong to the celestial Church, for they are able to receive it so as to perceive it, as was done by those living before the Flood who have consequently been segregated from everyone else and are kept in a hell separated from the hells of others - regarding which see 1265-1272. The prevention of the occurrence ever again of the profanation of good is meant by the reference to Jehovah expelling man and causing cherubim to dwell away from the east towards the garden of Eden, and the flame of a sword turning this way and that to guard the way of the tree of life, Genesis 3:24. On these matters, see 308, 310.
