Reform, Reconstructionist, or Humanistic) to modify this custom for the sake of egalitarianism, or for a same-gender couple. One adaptation of this tradition is for the bride to circle the groom three times, then for the groom to circle his bride three times, and then for each to circle each other (as in a do-si-do). The symbolism of the circling has been reinterpreted to signify the centrality of one spouse to the other, or to represent the four imahot (matriarchs) and three avot (patriarchs). Presentation of the ring (Betrothal) In traditional weddings, two blessings are recited before the betrothal; a blessing over wine, and the betrothal blessing, which is specified in the Talmud. The wine is then tasted by the couple. Rings are not actually required; they are simply the most common way (since the Middle Ages) of fulfilling the bride price requirement. The bride price (or ring) must have a monetary value no less than a single prutah (the smallest denomination of currency used during the Talmudic era). The low value is to ensure that there are no financial barriers to access marriage. According to Jewish law, the ring must be composed of solid metal (gold or silver are preferred; alloys are discouraged), with no jewel inlays or gem settings, so that it's easy to ascertain the ring's value. Others ascribe a more symbolic meaning, saying that the ring represents the ideal of purity and honesty in a relationship. However, it's quite common for Jewish couples (especially those who are not Orthodox) to use weddings rings with engraving, metallic embellishments, or to go a step further and use gemstone settings. Some Orthodox couples will use a simple gold or silver band during the ceremony to fulfill the halachic obligations, and after the wedding, the bride may wear a ring with any decoration she likes. The groom gives the bride a ring, traditionally a plain wedding band, and recites the declaration: Behold, you are consecrated to me with this ring according to the law of Moses and Israel. The groom places the ring on the bride's right index finger. According to traditional Jewish law, two valid witnesses must see him place the ring. During some egalitarian weddings, the bride will also present a ring to the groom, often with a quote from the Song of Songs: "Ani l'dodi, ve dodi li" (I am my beloved's and my beloved is mine),
