'Seventh' in the Bible

So the priests, and the Levites, and the porters, and the singers, and some of the people, and the Nethinim, and all Israel, lived in their cities. When the seventh month was come, the children of Israel were in their cities.

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

They found written in the law, how that Yahweh had commanded by Moses, that the children of Israel should dwell in booths in the feast of the seventh month;

and if the peoples of the land bring wares or any grain on the Sabbath day to sell, that we would not buy of them on the Sabbath, or on a holy day; and that we would forego the seventh year, and the exaction of every debt.
