Secondly, there is no requirement anywhere....Old or New Testament for wedding ceremonies or vows. If a couple meet and start kissing, fondling and have sexual intercourse....and they stay together....they are married. That is what happened in the biblical era, then there was also arrangements by fathers that occurred a lot of times. LOL It was usually a delivery. The groom paid a bride price and the father was required to deliver a virgin daughter. The Hebrew language did not have a word for wed or wedding.
The Process of Marriage: Kiddushin and Nisuin
The process of marriage occurs in two distinct stages: kiddushin (commonly translated as betrothal) and nisuin (full-fledged marriage). Kiddushin occurs when the woman accepts the money, contract or sexual relations offered by the prospective husband. The word "kiddushin" comes from the root Qof-Dalet-Shin, meaning "sanctified." It reflects the sanctity of the marital relation. However, the root word also connotes something that is set aside for a specific (sacred) purpose, and the ritual of kiddushin sets aside the woman to be the wife of a particular man and no other.
Kiddushin is far more binding than an engagement as we understand the term in modern English; in fact, Rambam speaks of a period of engagement before the kiddushin. Once kiddushin is complete, the woman is legally the wife of the man. The relationship created by kiddushin can only be dissolved by death or divorce. However, the spouses do not live together at the time of the kiddushin, and the mutual obligations created by the marital relationship do not take effect until the nisuin is complete.
The nisuin (from a word meaning "elevation") completes the process of marriage. The husband brings the wife into his home and they begin their married life together.
In the past, the kiddushin and nisuin would routinely occur as much as a year apart. During that time, the husband would prepare a home for the new family. There was always a risk that during this long period of separation, the woman would discover that she wanted to marry another man, or the man would disappear, leaving the woman in the awkward state of being married but without a husband. Today, the two ceremonies are normally performed together.

If you don't understand this then you miss many of the allusions to it in the NT.
