 And a Tanna taught before Rav Nachman that when one vexes one's father and mother, God considers it right not to dwell among them, for had God dwelt among them, they would have vexed God.The Mekhilta of Rabbi Ishmael taught that there are four types of children (as evinced by the four times — in and — that Scripture reports telling a child) — the wise, the simple, the wicked, and the type who does not know how to ask.The wise child asks, in the words of “What mean the testimonies, and the statutes, and the ordinances, that the Lord our God has commanded you?” The Mekhilta taught that we explain to this child all the laws of Passover.
