This passage in Ezekiel describes several parts of the wedding: the covenant, the baptism, the "fine linen", the ornate clothing of royalty, the crown, and the presentation of the bride to the nations.
Now when I passed by thee, and looked upon thee, behold, thy time was the time of love; and I spread my skirt over thee, and covered thy nakedness: yea, I sware unto thee, and entered into a covenant with thee, saith the Lord יהוה YAHVEH , and thou becamest mine. Then washed I thee with water; yea, I throughly washed away thy blood from thee, and I anointed thee with oil. I clothed thee also with broidered work, and shod thee with badgers' skin, and I girded thee about with fine linen, and I covered thee with silk. I decked thee also with ornaments, and I put bracelets upon thy hands, and a chain on thy neck. And I put a jewel on thy forehead, and earrings in thine ears, and a beautiful crown upon thine head. Thus wast thou decked with gold and silver; and thy raiment was of fine linen, and silk, and broidered work; thou didst eat fine flour, and honey, and oil: and thou wast exceeding beautiful, and thou didst prosper into a kingdom. And thy renown went forth among the heathen for thy beauty: for it was perfect through my comeliness, which I had put upon thee, saith the Lord יהוה YAHVEH . Ezekiel 16:8-14

There is a rapture at a baptism
And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him.

But Philip was found at Azotus: and passing through he preached in all the cities, till he came to Caesarea. Acts:8: 38-40
