'Seventh' in the Bible
All the men of Israel assembled themselves to the king at the feast, that is in the seventh month.
Then on the twenty-third day of the seventh month he sent the people to their tents, rejoicing and happy of heart because of the goodness that the Lord had shown to David and to Solomon and to His people Israel.
Now in the seventh year Jehoiada strengthened himself, and took captains of hundreds: Azariah the son of Jeroham, Ishmael the son of Johanan, Azariah the son of Obed, Maaseiah the son of Adaiah, and Elishaphat the son of Zichri, and they entered into a covenant with him.
In the third month they began to make the heaps, and finished them by the seventh month.
