The pillars did not survive the destruction of the First Temple; Jeremiah 52:17 reports: "The Chaldeans broke up the bronze columns of the House of the Lord".
[3] According to rabbi Raymond Apple, "Jewish commentators on I Kings 7:21 maintain that it was when one stood inside the building and looked out toward the entrance in the east" that Jachin was on the right (to the south) and Boaz was on the left (to the north).
[5] An explanatory note by William Whiston on paragraph 6 of the same chapter,[6] explains this as agreeing with the opinion of the Jewish commentators.
[4] The Romanesque Church of Santa Maria Maggiore at Tuscania, Italy, has a recessed entrance flanked by a pair of free-standing stone columns intended to evoke Boaz and Jachin.
[7] Similar pillars intended to represent Boaz and Jachin also exist in Würzburg Cathedral (Germany) and Dalby Church (Sweden).
