Haggai 2:3

Who is left? Since not quite 70 years (see on ch. 1:2) had elapsed since the destruction of the Temple, it is quite possible that some of the older people present had seen the former Temple in their childhood. Some commentators think that Haggai himself was old enough to have seen it. The difference between the magnificent “glory” of Solomon’s Temple and the disappointing appearance of this building must have brought deep sorrow to the people, such as they had felt at the laying of the foundation 15 years earlier (Ezra 3:11-13).

Nothing. Josephus states that the Second Temple was only half as high as Solomon’s Temple, and in many ways inferior to it (Antiquities viii. 3. 2; xv. 11. 1). However, the chief difference was not in size but in splendor of appearance and rich adornments of gold and precious stones.
