כִּֽי־בָנָ֣ה יְהוָ֣ה צִיּ֑וֹן נִ֝רְאָ֗ה בִּכְבוֹדֽוֹ׃
대저 여호와께서 시온을 건설하시고 그 영광 중에 나타나셨음이라
Rabbeinu Bahya
According to Bereshit Rabbah 56,11 the words בהר ה' יראה refer to two visions Yitzchak experienced of the two Temples being built as well as being in ruins. They base this on the verses (Lamentations 5,18) על הר ציון ששמם, “on the mountain of Zion which is in ruins”, and on Deut. 16,16 יראה כל זכורך, “everyone of your males shall appear there” ( the site of the Temple). A third verse describing the Temple as rebuilt is found in Psalms 102,17 כי בנה ה' ציון נראה בכבודו, “for the Lord has built Zion, He has appeared in all His glory.”
