Vulg. 1 Kgs 12:33

Et ascendit super altare quod exstruxerat in Bethel, quintadecima die mensis octavi, quem finxerat de corde suo: et fecit solemnitatem filiis Israël, et ascendit super altare, ut adoleret incensum.

And he went up to the altar, which he had built in Bethel, on the fifteenth day of the eighth month, which he had devised of his own heart: and he ordained a feast to the children of Israel, and went up on the altar to burn incense.
