Nehemiah 8:13-14

13On the second day of the seventh month, the leaders of families met together. They met with the priests, the Levites and with Ezra. They wanted to study the message of God's Law.

14They discovered what the Lord had commanded about a certain feast. The Lord had told Moses that the Israelites should live in huts during this feast. They should do that in the seventh month of each year.
