When Pharaoh had enough of the plagues he told Moshe he can take the people out of Egypt to go worship Hashem as he requested. He then asked, מִי וָמִי הַהֹלְכִים, “…which ones are going?” He was surprised at the answer he got. Moshe replied, בִּנְעָרֵינוּ וּבִזְקֵנֵינוּ נֵלֵךְ, “With our youngsters and with our elders we will go…”. (Ex. 10,8-9)
Pharaoh’s surprise was because in his understanding it is only the elders who worship their gods. The youngsters have no part in their religion. Moshe informed Pharaoh that the youngsters are an integral part of our religion. When a child can utter words the child is taught to recite the Shema. When he gets a little older he is taught to read and to pray. He is given a Jewish education.
When the children are Bar or Bat Mitzvah they assume full responsibilities of our faith. It is a religion for all ages. In a true Jewish home the training starts as soon as the child can speak. We have a special Mitzvah for parents of Chinuch – training or education. You cannot expect a child who grows up to suddenly cast upon it the obligations of Mitzvot without previous training. It is also noteworthy that in Judaism the obligation to learn never ends.
This was all strange to Pharaoh and he could not understand why Moshe insisted that even the children be allowed to go out of Egypt to worship Hashem.
