'Seventh' in the Bible

On the first day of the seventh month, Ezra the priest brought the law before the assembly of men, women, and all who could listen with understanding.

They found written in the law how the Lord had commanded through Moses that the Israelites should dwell in booths during the festival of the seventh month.

When the surrounding peoples bring merchandise or any kind of grain to sell on the Sabbath day, we will not buy from them on the Sabbath or a holy day. We will also leave the land uncultivated in the seventh year and will cancel every debt.
