Machshava:

Pesach 

Description

The words signifying the order of the Seder are well known. We begin with Kadesh/Sanctifying the Seder night over wine, continuing with another eleven or thirteen and ending with Nirtzah. In the entire order, there is only one segment that is split, being interrupted by the meal and Birkat Hamazon, and then resuming. This anomaly is very strange, as Hallel is not supposed to be divided. Further, if it is divided, why not proclaim its order where it begins, prior to the festive meal, instead of afterward? And we generally precede the Hallel with a blessing; why do we not do so during the Seder?
