TSK · 2 Chronicles 7:9

Seven days thou shalt make atonement for the altar, and sanctify it: and the altar shall be most holy; whatsoever toucheth the altar shall be holy.

Six days thou shalt eat unleavened bread; and on the seventh day shall be a solemn assembly to Jehovah thy God; thou shalt do no work [therein] .

So Solomon held the feast at that time, and all Israel with him, a great assembly, from the entrance of Hamath unto the brook of Egypt, before Jehovah our God, seven days and seven days, even fourteen days.

Also day by day, from the first day unto the last day, he read in the book of the law of God. And they kept the feast seven days; and on the eighth day was a solemn assembly, according unto the ordinance.
