   In Luke 22:11 and Mark 14:14, the nominative singular neuter form occurs in the question directed to a householder about the place where the Teacher may eat the Passover with his disciples; the APB renders the clause "Where is the guest room." In Luke 2:7, the dative singular neuter form occurs in the reason given for laying the child in a manger, and the APB renders "there was no place for them in the guest room."

In the Anselm Project Bible: Across all three verses, the APB presents the relevant place as a "guest room." This rendering confirms the verses' setting but does not by itself fix a finer distinction.
