Comentario sobre Exodo 33:10

והשתחוו AND THEY PROSTRATED THEMSELVES to the Shechinah.

והשתחוו איש פתח אהלו, “and they would prostrate themselves, each one at the entrance to his tent.” They did not bow down and prostrate themselves on account of the presence of the pillar of fire or the pillar of cloud, but as a sign of respect for the attribute of כבוד which was present in Moses’ tent. The matter is similar to the respect we show to the Torah scroll. When we bow down before it we do not mean to honour the scroll but what the scroll represents, i.e. the word of G’d which is written on the parchment.

To the Shechinah. I.e., not to the entrance of Moshe’s tent, as איש פתח אהלו seemingly implies. The only reason it says איש פתח אהלו is because the Pillar of Cloud was there [i.e., at the entrance of Moshe’s tent].
