פירוש על דברי הימים ב 6:1

Then Solomon said Since the House is full of smoke, I now know that the Shechinah is resting in the thick darkness therein, for so is His wont, as it is written (Exod. 20:18): “and Moses drew near to the thick darkness wherein God appeared.” [Therefore, I deduce that] He surely wishes to stay therein, and in Sifre it is explained: Then Solomon said - when he saw the cloud, he said, “Now I see that the Shechinah rests in the House that I have built, for He promised to come and dwell therein out of the midst of the cloud and the thick darkness.” Now where did He say this? (Lev. 16:2): “for in the cloud I shall appear on the Ark cover.”
