**In year** 18 of his reign, which was year 3742, he began the building of the House of HaShem. [(And in Yuchsin Ma'amar 5 section 6, in the 15th year of his reign he built the Temple, and he took out much gold from the grave of David).] And with his own hands he began the work of the foundations of the Temple, and after him all the princes of Yehudah and the elders and sages as day laborers. And the work was completed at the end of 8 years (year 3750), and HaShem did not bring rain all those years during the day, only at night [(Ta'anit 23a) (Tzeda).
And in Sha'ar HaDorot 25 writes 2 - in the year that was about 100 years before the destruction of the Second Temple, for he reigned (it should read 102) years before the destruction and built the Temple anew, etc. And see Tosafot first chapter of Bava Batra (end of daf 4) that he reigned 102 years before the destruction as is stated in the first chapter of Avodah Zarah. And what is written that he reigned 40 years, it should read 37, for he reigned in year 3724 and the 18th year of his reign was year 3742 when he built the Temple, and he reigned 37 years and died in year 3761, and the destruction was in year 3828.
Thus he reigned 104 years before the destruction, and the Temple that he built stood 78 years from when it was completed - check to correct his words].
