Erusin

Erusin is the Hebrew term for betrothal. In modern Hebrew, "erusin" means engagement, but this is not the historical meaning of the term, which is the first part of marriage (the second part being nissuin).

Since the Middle Ages it is customary for the marriage to occur immediately after the betrothal, and to perform the betrothal during the marriage ceremony itself. Previously this was not the case, and there were often several months between the two events.

In Hebrew and classical rabbinic literature, betrothal is frequently referred to as sanctification (Hebrew: Kiddushin, קידושין), on account of the bride becoming "sanctified" (dedicated) to the groom.

In the Hebrew Bible
In the book of Deuteronomy, the concept of erusin is introduced. This holds the couple accountable to the law against adultery, which is punishable by death, while not fully considering them as married.

An untraditional view is that the betrothal was effected simply by purchasing the girl from her father (or guardian) (i.e., paying a bride price to the bride and her father). The price paid for her is known by the Hebrew term mohar. It was customary in biblical times for the bride and her father to be given parts of the mohar. Gradually, it lost its original meaning, and the custom arose of giving the mohar entirely to the bride rather than her father.

The traditional commentators do not necessarily explain mohar this way. Rashi understands mohar as a form of ketubah (an agreement to pay a certain amount upon divorce), and Nachmanides understands it as sovlanut (a sort of dowry or engagement present). Rashi understands Rachel and Leah's complaint to Jacob ("we are considered strangers to him for he has sold us" ) as saying that it was not normal for a father to sell his daughters—at least not without also giving them a dowry.

Consent from a betrothed woman is not explicitly mentioned as a requirement in the Bible, but permission to forgo consent is not explicitly permitted either. That said, after encountering Rebekah (Genesis 24:15-16), Abraham's servant sought permission from her family for her to accompany him and become the wife of Isaac (Genesis 24:58).

The legal act
The Talmud states that there are three methods of performing erusin: by handing the woman a coin or object of nominal value, by handing her a document, or through consummation (sexual intercourse), although the last is prohibited by the Talmud because it is considered to be indecent for witnesses to watch a couple having intercourse: erusin ceremonies are to be confirmed by two witnesses. In all cases, the woman's consent is required; however, it can be implied by her silence.

The blessings
The erusin is preceded by a blessing over wine and then the bircat erusin (betrothal blessing). If forgotten before the ceremony, it can be recited before the ketubah is read. Originally, the blessings were recited by the groom, but today it is more common for someone else to recite them such as the wedding's Rabbi.

The betrothal
Today, the custom is to perform the betrothal by giving the bride an object whose value is well known, and fairly constant: a gold ring without a stone. This is in accordance with the first method mentioned above.

The actual betrothal now takes place. The groom takes the ring and says in Hebrew, Behold, you are consecrated to me with this ring according to the laws of Moses and Israel. The groom now places the ring on the bride’s index finger.

The ketubah
In order to separate the erusin and nissuin - the two parts of the wedding - the ketubah is read.

Other issues
For legal purposes, a betrothed couple are regarded as husband and wife. Similarly, the union can only be ended by the same divorce process as for married couples. However, betrothal does not oblige the couple to behave towards each other in the manner that a married couple is required to, nor does it permit the couple to have a sexual relationship with each other.

The rabbis prohibited marrying without an engagement (shiddukhin). Therefore, an old custom is to sign a Shetar haT'na'im as a formal form of engagement, forming an informal declaration of the couple's intentions, and is read close to the start of the betrothal ceremony.
