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.

1468. 'That he said to Sarai his wife' means that He thought in the following way about truths to which celestial things were allied. This is clear from the meaning of 'Sarai' when she is called 'a wife'. In the internal sense of the Word 'a wife' means nothing other than truth joined to good, for truth joined to good is altogether like a marriage. When the noun 'husband' (maritus) is used in the Word it means good and 'wife' means truth. But when instead of this another noun for 'husband' (vir) is used, it in that case means truth, and 'wife' means good; and this is a consistent usage in the Word, as also stated already in 915. Since 'Abram' has been mentioned by name in this passage, 'Sarai his wife' means truth. Thus the meaning of 'he said to Sarai his wife' is in the internal sense that He thought in the following way about truths to which celestial things were allied. It is true historically that when he travelled into Egypt Abram spoke to his wife in this way; but, as has been stated, all the historical events recorded in the Word are representative and every word carries a spiritual meaning. No other historical details have been brought in, and those that have are not presented in any other sequence, nor expressed in any other words than such as in the internal sense may express these arcana.
