2 Chronicles 7:10

And all the men of Israel assembled themselves to King Solomon at the feast, in the month Ethanim, which is the seventh month.

Now the king and all Israel with him were offering sacrifices before Yahweh.

And all the men of Israel assembled themselves to the king at the feast, that is in the seventh month.

So there was great gladness in Jerusalem, because there was nothing like this in Jerusalem since the days of Solomon the son of David, king of Israel.

“In the seventh month, on the fifteenth day of the month, at the feast, he shall provide like this, seven days for the sin offering, the burnt offering, the grain offering, and the oil.”
