Musar su Salmi 65:5

It was taught: That entire day none of them went out of the house, to which was attached a pillar of smoke. They rejoiced in the novel insights that were revealed as if they had received the Torah from Mount Sinai that very day. As they were bringing the infant to the synagogue they heard a voice. It was that of the prophet Eliyahu reciting the verse, “Fortunate is the one whom You choose and draw close that he may dwell in Your courtyards; may we be satiated with the goodness of Your House, the holy place of Your Sanctuary” (Tehillim 65:5). This verse contains deep esoteric allusions, for it contains forty-two letters corresponding to the forty-two letter Name, the meaning of which may only be revealed to the circumspect. It also contains ten words, corresponding to which the Zohar teaches that when it is recited at the time of a circumcision the infant is crowned with ten canopies that will await him in the World to Come.
