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.

709. The name Jehovah is used because now the subject is charity. From verse 9 to the end of the previous chapter Jehovah is not used but God, the reason being that there the subject is the preparation of Noah, or the member of the Church called Noah, as regards things of his understanding, which are matters of faith. Here however it is the preparation of him as regards the things of his will, which are matters of love. When the subject is the things of the understanding, that is, the truths of faith, the name God is used, but when it is those of the will, that is, goods stemming from love, Jehovah is used. For it is not things of the understanding, that is, of faith, that constitute the Church but those of the will which are matters of love. Jehovah is present within love and charity, but not within faith except faith that inheres in love or charity. This also is why in the Word faith is compared to the night, but love to the daytime, as in Genesis 1 where the great lights are mentioned; the greater light, which is the sun and means love, has dominion over the day, while the lesser light, which is the moon and means faith, has dominion over the night, Genesis 1:14, 16. Similarly in the Prophets, Jeremiah 31:35; 33:20; Psalms 136:8-9; also Revelation 8:12.
