פירוש על שבת 45:10

A courtyard that has two entrances That the house has two entrances opening on to the courtyard. [Hence it] needs two lamps - one lamp for each entrance - on account of suspicion, as the reason is explained. For the one looking would think that the house is divided, and it surely belongs to two people. So they will say [that] one is not fulfilling the commandment of the lamp.

From two different directions: One in the north and one in the east.

The suspicion of people: The residents of another city, who pass through from there in the marketplace.

Even facing the same direction as well, they will think that the house is divided inside it.

And if it is the suspicion of the residents of the city who know that there is no division.
