John 10:23

Solomon's porch - By what we find in Josephus, Ant. b. xx. c. 8, s. 7, a portico built by Solomon, on the east side of the outer court of the temple, was left standing by Herod, when he rebuilt the temple. This portico was four hundred cubits long, and was left standing, probably, because of its grandeur and beauty. But when Agrippa came to Jerusalem, a few years before the destruction of the city by the Romans, and about eighty years after Herod had begun his building, (till which time what Herod had begun was not completed), the Jews solicited Agrippa to repair this portico at his own expense, using for argument, not only that the building was growing ruinous, but that otherwise eighteen thousand workmen, who had all of them, until then, been employed in carrying on the works of the temple, would be all at once deprived of a livelihood.

Solomon's porch - The porch or covered way on the east of the temple. See the notes at Matthew 21:12.

10:23 In Solomon's portico — Josephus informs us, that when Solomon built the temple, he filled up a part of the adjacent valley, and built a portico over it toward the east. This was a noble structure, supported by a wall four hundred cubits high: and continued even to the time of Albinus and Agrippa, which was several years after the death of Christ.
