From a Parent to a Child - The Best Segula for Emunah

והגדת לבנך - “And you should tell to your son” (Shemos 13:8) Is this verse telling us that the story of yetzias Mitzrayim should be told by a parent to his child, simply because a parent knows more? Based on the Rambam, we learn that it is not so. Even when a child knows more than a parent, it is still better for the story of yetzias Mitzrayim to be told specifically by a parent. The reason for this is because on the first night of Pesach, there is a special segulah for emunah when the story of yetzias Mitz- rayim is related specifically by a parent to his child.

[Nesivos Shalom, Pesach, §7]
