'Seventh' in the Bible

When the seventh month arrived and the Israelites were settled in their cities,

So Ezra the priest brought the law before the assembly which included men and women and all those able to understand what they heard. (This happened on the first day of the seventh month.)

They discovered written in the law that the LORD had commanded through Moses that the Israelites should live in temporary shelters during the festival of the seventh month,

We will not buy on the Sabbath or on a holy day from the neighboring peoples who bring their wares and all kinds of grain to sell on the Sabbath day. We will let the fields lie fallow every seventh year, and we will cancel every loan.
