Thus it is first in time, and therefore first in respect to a blessing too.');"><sup>10</sup></span> But Beth Hillel maintain: He recites a blessing over the wine and then recites a blessing for the day, because the wine enables the kiddush to be recited.<span class="x" onmousemove="('comment',' without wine or bread kiddush cannot be said. Bread is the equivalent of wine in this respect, and the blessing for bread precedes the blessing for the day.');"><sup>11</sup></span> Another reason: the blessing for wine is constant, while the blessing for the day is not constant ,<span class="x" onmousemove="('comment',' Whenever 'wine is drunk a blessing over it is required, whereas the blessing of sanctification is confined to festivals.');"><sup>12</sup></span>
