Musar su Salmi 118:19

Rabbi Yehudah said: There are seven categories of ministering angels at the gates that are called “the Gates of Righteousness.” It was over these that Dovid HaMelech claimed, “Open for me the Gates of Righteousness! I will enter them and give thanks to God. This is the Gate of Hashem; the righteous shall enter it” (Tehillim 118:19-21). And there are seven gates through which the souls of the righteous enter into Gan Eden until they reach a place that is commensurate with their station. At every gate there are guards. Through the first gate the soul enters into the Cave of Machpelah (the Tomb of the Patriarchs), which is near Gan Eden. Adam HaRishon stands guard over it. If the soul merits, Adam HaRishon proclaims, “Make way for the pious one! Come in peace!” Then the soul exits the first gate and enters the second gate of Gan Eden. There the cherubim and the flame of the revolving sword stand guard.
