BEAUTIFUL GATE

How the people that were eye-witnesses of this miracle were influenced by it we are next told. 1. They were entirely satisfied in the truth of the miracle, and had nothing to object against it. They knew it was he that sat begging at the beautiful gate of the temple, Act_3:10. He had sat there so long that they all knew him; and for this reason he was chosen to be the vessel of this mercy. Now they were not so perverse as to make any doubt whether he was the same man, as the Pharisees had questioned concerning the blind man that Christ cured, Joh_9:9, Joh_9:18. They now saw him walking, and praising God (Act_3:9), and perhaps took notice of a change in his mind; for he was now as loud in praising God as he had before been in begging relief. The best evidence that it was a complete cure was that he now praised God for it. Mercies are then perfected, when they are sanctified. 2. They were astonished at it: They were filled with wonder and amazement (Act_3:10); greatly wondering, Act_3:11. They were in an ecstasy. There seems to have been this effect of the pouring out of the Spirit, that the people, at least those in Jerusalem, were much more affected with the miracles the apostles wrought than they had been with those of the same kind that had been wrought by Christ himself; and this was in order to the miracles answering their end. 3. They gathered about Peter and John: All the people ran together unto them in Solomon's porch: some only to gratify their curiosity with the sight of men that had such power; others with a desire to hear them preach, concluding that their doctrine must needs be of divine origin, which thus had a divine ratification. They flocked to them in Solomon's porch, a part of the court of the Gentiles, where Solomon had built the outer porch of the temple; or, some cloisters or piazzas which Herod had erected upon the same foundation upon which Solomon had built the stately porch that bore his name, Herod being ambitious herein to be a second Solomon. Here the people met, to see this great sight.
From Henry Matthew's Commentary

(1) Wall, “Hel,” “Soregh,” Gates.
In the upper or northerly part of this large area, on a much higher level, bounded likewise by a wall, was a second or inner enclosure - the “sanctuary” in the stricter sense (Josephus, BJ, V, v, 2) - comprising the court of the women, the court of Israeland the priests' court, with the temple itself (Josephus, Ant., XV, xi, 5). The surrounding wall, according to Josephus (BJ, V, v, 2), was 40 cubits high on the outside, and 25 on the inside - a difference of 15 cubits; its thickness was 5 cubits. Since, however, the inner courts were considerably higher than the court of the women, the difference in height may have been some cubits less in the latter than in the former (compare the different measurements in Kennedy, ut supra, 182), a fact which may explain the difficulty felt as to the number of the steps in the ascent (see below). Round the wall without, at least on three sides (some except the West), at a height of 12 (Mid.) or 14 (Jos) steps, was an embankment or terrace, known as the ḥēl (fortification), 10 cubits broad (Mid. says 6 cubits high), and enclosing the whole was a low balustrade or stone parapet (Josephus says 3 cubits high) called the ṣōrēgh, to which were attached at intervals tablets with notices in Greek and Latin, prohibiting entry to foreigners on pain of death (see PARTITION, WALL OF). From within the ṣōrēgh ascent was made to the level of the ḥēl by the steps aforesaid, and five steps more led up to the gates (the reckoning is probably to the lower level of the women's court). Nine gates, with two-storied gatehouses “like towers” (Josephus, BJ, V, v, 3), are mentioned, four on the North, four on the South, and one on the East - the last probably to be identified, though this is still disputed (Waterhouse, etc.), with the “Gate of Nicanor” (Mid.), or “Corinthian Gate” (Jos), which is undoubtedly “the Beautiful Gate” of Act_3:2, Act_3:10 (see for identification, Kennedy, ut supra, 270). This principal gate received its names from being the gift of a wealthy Alexandrian Jew, Nicanor, and from its being made of Corinthian brass. It was of great size - 50 cubits high and 40 cubits wide - and was richly adorned, its brass glittering like gold (Mid., ii. 3). See BEAUTIFUL GATE. The other gates were covered with gold and silver (Josephus, BJ, V, v, 3).
