John Gill Bible Commentary

And three times in a year did Solomon offer burnt offerings and peace offerings upon the altar which he built unto the Lord,.... The brasen altar, the altar of burnt offering, which stood in the court of the priests, and by whom he offered. The three times were the feasts of passover, pentecost, and tabernacles, as explained in Ch2 8:13, not that these were the only offerings, or these the only times he offered; for he offered all other sacrifices, and at all other times commanded in the law of Moses, as on sabbaths and new moons, as expressed in the above place: and he burnt incense upon the altar that was before the Lord; the altar of incense, which stood in the holy place, right beside the most holy, in which was the ark, the symbol of the divine Presence; not that Solomon burnt incense in person, but by the priests, whom he furnished with incense; for no king might offer incense, as the case of Uzziah shows: so he finished the house; which respects not the building of it, that had been observed before, but the service of it; as he had provided all vessels and utensils for the furniture of it, and all things to be used in them; as sacrifices for the altar of burnt offering, incense for the altar of incense, bread for the shewbread table, and oil for the lamps; so he appointed the courses of the priests, Levites, and porters, to do their duty, who went through every part of service assigned them, and completed the whole; see Ch2 8:14.
