'Seventh' in the Bible

All the men of Israel assembled before King Solomon at the festival in the month of Ethnaim, that is, the seventh month.

It happened that at the seventh time, he said, "Look, there is a small cloud, as [the] hand of a man, coming up from the sea." Then [Elijah] said, "Go up, say to Ahab, 'Harness [your horses] and go down, lest the rain stop you.'"

These encamped opposite for seven days, and it happened on the seventh day that {the battle began}, and the {Israelites} killed the Arameans, one hundred thousand infantry in one day.
