The inn where there was no room [meant] there was no spiritual nourishment at that time, because everything of the Word, and so everything of worship with them, had by then been adulterated and perverted. (De Verbo 7)

In Luke 2:7; 10:34, this signifies that there was no instruction from the Jewish church as it was then in mere falsities from the adulteration of the Word. (Apocalypse Explained 796[12])
