פּירוש אויף חגי 1:8

and I will be honored The “heh” [whose numerical value is five] missing from the Masoretic text corresponds to the five items in the First Temple that were not in the Second Temple: 1) the Holy Ark, 2) the Urim and Tummim, 3) the fire that descended from heaven, 4) the Shechinah, and 5) the Holy Spirit, as is stated in Tractate Yoma (21b).
