TSK · 2 Chronicles 7:5

The king, and all Israel with him, offered sacrifice before Yahweh.

Solomon went up there to the bronze altar before Yahweh, which was at the Tent of Meeting, and offered one thousand burnt offerings on it.

King Solomon and all the congregation of Israel, that were assembled to him, were before the ark, sacrificing sheep and cattle, that could not be counted nor numbered for multitude.

The number of the burnt offerings which the assembly brought was seventy bulls, one hundred rams, and two hundred lambs: all these were for a burnt offering to Yahweh.

Josiah gave to the children of the people, of the flock, lambs and young goats, all of them for the Passover offerings, to all who were present, to the number of thirty thousand, and three thousand bulls: these were of the king's substance.

It shall be the prince's part to give the burnt offerings, and the meal offerings, and the drink offerings, in the feasts, and on the new moons, and on the Sabbaths, in all the appointed feasts of the house of Israel: he shall prepare the sin offering, and the meal offering, and the burnt offering, and the peace offerings, to make atonement for the house of Israel.

It was the Feast of the Dedication at Jerusalem.
