TSK · 2 Chronicles 7:9

For seven days you are to make atonement for the altar and set it apart as holy. Then the altar will be most holy. Anything that touches the altar will be holy.

You must eat bread made without yeast for six days. The seventh day you are to hold an assembly for the LORD your God; you must not do any work on that day.

At that time Solomon and all Israel with him celebrated a festival before the LORD our God for two entire weeks. This great assembly included people from all over the land, from Lebo Hamath in the north to the Stream of Egypt in the south.

Ezra read in the book of the law of God day by day, from the first day to the last. They observed the festival for seven days, and on the eighth day they held an assembly as was required.
