"a portico," is used (a) of the "porches" at the pool of Bethesda, John 5:2; (b) of the covered colonnade in the Temple, called Solomon's "porch," John 10:23; Acts 3:11; 5:12 a portico on the eastern side of the temple; this and the other "porches" existent in the time of Christ were almost certainly due to Herod's restoration. Cp. Stoics ( Acts 17:18 ), "philosophers of the porch."

akin to pule, "a gate" (Eng., "pylon"), is used of "a doorway, porch or vestibule" of a house or palace, Matthew 26:71 . In the parallel passage Mark 14:68 , No. 3 is used, and pulon doubtless stands in Matthew 26 for proaulion. See GATE , No. 2.

3: προαύλιον

(Strong's #4259 — Noun Neuter — proaulion — pro-ow'-lee-on )

"the exterior court" or "vestibule," between the door and the street, in the houses of well-to-do folk, Mark 14:68 , "porch" (RV marg., "forecourt").
